European ASP.NET MVC 6 Hosting - :: Use AngularJS with MVC 6 Web API

clock February 10, 2017 08:46 by author Scott

This post will walk you through the step-by-step procedure on building a simple ASP.NET 5 application using AngularJS with Web API.

Before we dig further let’s talk about a quick overview of AngularJS and Web API in MVC 6.

Introducing AngularJS

AngularJS is a client-side MVC framework written in JavaScript. It runs in a web browser and greatly helps us (developers) to write modern, single-page, AJAX-style web applications. It is a general purpose framework, but it shines when used to write CRUD (Create Read Update Delete) type web applications.

Introducing Web API

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework. In ASP.NET 5, Web API is now part of MVC 6. Read more here

Creating an ASP.NET 5 Project

To start, fire up Visual Studio 2015 and create a new ASP.NET 5 project by selecting File > New Project. In the dialog, under Templates > Visual C#, select ASP.NET Web Application as shown in the figure below: 

Name your project to whatever you like and then click OK. For this example I named the project as “AngularJS101”. Now after that you should be able to see the “New ASP.NET Project” dialog:

Now select ASP.NET 5 Preview Empty template from the dialog above. Then click OK to let Visual Studio generate the necessary files and templates needed for you. You should be able to see something like below:

Adding the Scripts folder

The next thing to do is to create a new folder called “Scripts”. This folder will contain all the JavaScript files needed in our application:

Getting the Required Packages

ASP.NET 5 now supports three main package managers: NuGet, NPM and Bower.

Package Manager

A package manager enables you to easily gather all resources that you need for building an application. In other words you can make use of package manager to automatically download all the resources and their dependencies instead of manually downloading project dependencies such as jQuery, Bootstrap and AngularJS in the web.


NuGet manages .NET packages such as Entity Framework, ASP.NET MVC and so on. You typically specify the NuGet packages that your application requires within project.json file.


NPM is one of the newly supported package manager in ASP.NET 5. This package manager was originally created for managing packages for the open-source NodeJS framework. The package.json is the file that manages your project’s NPM packages.


Bower is another supported package manager in ASP.NET 5. It was created by Twitter that is designed to support front-end development. You can use Bower to manage client-side resources such as jQuery, AngularJS and Bootstrap.

For this example we need to use NPM to install the resources we need in our application such as Grunt and the Grunt plugins. To do this just right click in your Project (in this case AngularJS101) and select Add > New Item. In the dialog select NPM configuration file as shown in the figure below:

Click Add to generate the file for you. Now open package.json file and modify it by adding the following dependencies:

    "version": "1.0.0",
    "name": "AngularJS101",
    "private": true,
    "devDependencies": {
        "grunt": "0.4.5",
        "grunt-contrib-uglify": "0.9.1",
        "grunt-contrib-watch": "0.6.1"

Notice that you get Intellisense support while you edit the file. A matching list of NPM package names and versions shows as you type.

In package.json file, from the code above, we have added three (3) dependencies named grunt, grunt-contrib-uglify and grunt-contrib-watch NPM packages that are required in our application.

Now save the package.json file and you should be able to see a new folder under Dependencies named NPM as shown in the following:

Right click on the NPM folder and select Restore Packages to download all the packages required. Note that this may take a bit to finish the download so just be patient and wait ;). After that the grunt, grunt-contrib-uglify and grunt-contrib-watch NPM packages should now be installed as shown in the following:

Configuring Grunt

Grunt is an open-source tool that enables you to build client-side resources for your project. For example, you can use Grunt to compile your LESS or Saas files into CSS. Adding to that, Grunt can also be used to minify CSS and JavaScript files.

In this example, we will use Grunt to combine and minify JavaScript files. We will configure Grunt so that it will take all the JavaScript files from the Scripts folder that we created earlier, combine and minify the files, and finally save the results to a file named app.js within the wwwroot folder.

Now right click on your project and select Add > New Item. Select Grunt Configuration file from the dialog as shown in the figure below:

Then click Add to generate the file and then modify the code within the Gruntfile.js file so it will look like this:

module.exports = function (grunt) { 

        uglify: {
            my_target: {
                files: { 'wwwroot/app.js': ['Scripts/app.js', 'Scripts/**/*.js'] }

        watch: {
            scripts: {
                files: ['Scripts/**/*.js'],
                tasks: ['uglify']

    grunt.registerTask('default', ['uglify', 'watch']);

The code above contains three sections. The first one is used to load each of the Grunt plugins that we need from the NPM packages that we configured earlier. The initConfig() is responsible for configuring the plugins. The Uglify plugin is configured so that it combines and minifies all the files from the Scripts folder and generate the result in a file named app.js within wwwroot folder. The last section contains the definitions for your tasks. In this case we define a single ‘default’ task that runs ‘uglify’ and then watches for changes in our JavaScript file.

Now save the file and let’s run the Grunt file using Visual Studio Task Runner Explorer. To do this, go to View > Other Windows > Task Runner Explorer in Visual Studio main menu. In the Task Runner Explorer make sure to hit the refresh button to load the tasks for our application. You should see something like this:

Now right click on the default task and select Run. You should be able to see the following output:

Configuring ASP.NET MVC

There are two main files that we need to modify to enable MVC in our ASP.NET 5 application.

First, we need to modify the project.json file to in include MVC 6 under dependencies:

    "webroot": "wwwroot",
    "version": "1.0.0-*",
    "dependencies": {
        "Microsoft.AspNet.Server.IIS": "1.0.0-beta3",
        "Microsoft.AspNet.Mvc": "6.0.0-beta3"
    "frameworks": {
        "aspnet50": { },
        "aspnetcore50": { }

Make sure to save the file to restore the packages required. The project.json file is used by the NuGet package manager to determine the packages required in your application. In this case we’ve added Microsoft.AspNet.Mvc.

Now the last thing is to modify the Startup.cs file to add the MVC framework in the application pipeline. Your Startup.cs file should now look like this:

using System; 
using Microsoft.AspNet.Builder; 
using Microsoft.AspNet.Http; 
using Microsoft.Framework.DependencyInjection;

namespace AngularJS101 
    public class Startup
        public void ConfigureServices(IServiceCollection services){

        public void Configure(IApplicationBuilder app){

The ConfigureServices() method is used to register MVC with the ASP.NET 5 built-in Dependency Injection Framework (DI). The Configure() method is used to register MVC with OWIN.

Adding Models

The next step is to create a model that we can use to pass data from the server to the browser/client. Now create a folder named “Models” under the root of your project. Within the “Models” folder, create a class named “DOTAHero” and add the following code below:

using System;

namespace AngularJS101.Models 
    public class DOTAHero
        public int ID { get; set; }
        public string Name { get; set; }
        public string Type { get; set; }

Create another class called “HeroManager” and add the following code below:

using System.Collections.Generic; 
using System.Linq;

namespace AngularJS101.Models 
    public class HeroManager
        readonly List<DOTAHero> _heroes = new List<DOTAHero>() {
            new DOTAHero { ID = 1, Name = "Bristleback", Type="Strength"},
            new DOTAHero { ID = 2, Name ="Abbadon", Type="Strength"},
            new DOTAHero { ID = 3, Name ="Spectre", Type="Agility"},
            new DOTAHero { ID = 4, Name ="Juggernaut", Type="Agility"},
            new DOTAHero { ID = 5, Name ="Lion", Type="Intelligence"},
            new DOTAHero { ID = 6, Name ="Zues", Type="Intelligence"},
            new DOTAHero { ID = 7, Name ="Trent", Type="Strength"},
        public IEnumerable<DOTAHero> GetAll { get { return _heroes; } }

        public List<DOTAHero> GetHeroesByType(string type) {
            return _heroes.Where(o => o.Type.ToLower().Equals(type.ToLower())).ToList();

 public DOTAHero GetHeroByID(int Id) {
            return _heroes.Find(o => o.ID == Id);

The HeroManager class contains a readonly property that contains a list of heroes. For simplicity, the data is obviously static. In real scenario you may need to get the data in a storage medium such as database or any files that stores your data. It also contains a GetAll property that returns all the heroes and a GetHeroesByType() method that returns a list of heroes based on the hero type, and finally a GetHeroByID() method that returns a hero based on their ID.

Adding Web API Controller

For this particular example, we will be using Web API for passing data to the browser/client.

Unlike previous versions of ASP.NET, MVC and Web API controllers used the same controller base class. Since Web API is now part of MVC 6 then we can start creating Web API controllers because we already pulled the required NuGet packages for MVC 6 and configured MVC 6 in startup.cs.

Now add an “API” folder under the root of the project:

Then add a Web API controller by right-clicking the API folder and selecting Add > New Item. Select Web API Controller Class and name the controller as “HeroesController” as shown in the figure below:

Click Add to generate the file for you. Now modify your HeroesController class so it will look like this:

using System.Collections.Generic; 
using Microsoft.AspNet.Mvc; 
using AngularJS101.Models;

namespace AngularJS101.API.Controllers 
    public class HeroesController : Controller
        // GET: api/values
        public IEnumerable<DOTAHero> Get()
            HeroManager HM = new HeroManager();
            return HM.GetAll;

        // GET api/values/7
        public DOTAHero Get(int id)
            HeroManager HM = new HeroManager();
            return HM.GetHeroByID(id);


At this point we will only be focusing on GET methods to retrieve data. The first GET method returns all the heroes available by calling the GetAll property found in HeroManager class. The second GET method returns a specific hero data based on the ID.

You can test whether the actions are working by running your application in the browser and appending the /api/heroes in the URL. Here are the outputs for both GET actions:

Route: /api/heroes

Route: /api/heroes/7

Creating an AngularJS Application

Visual Studio 2015 includes templates for creating AngularJS modules, controllers, directives and factories. For this example we will be displaying the list of heroes using an AngularJS template.

Adding an AngularJS Module

To get started lets create an AngularJS module by right-clicking on the Scripts folder and selecting Add > New Item. Select AngularJS Module as shown in the figure below.

Click Add to generate the file and copy the following code for our AngularJS module:

(function () {
    'use strict';

    angular.module('heroesApp', [

The code above defines a new AngularJS module named “heroesApp”. The heroesApp has a dependency on another AngularJS module named “heroesService” which we will create later in the next step.

Adding an AngularJS Controller

The next thing to do is to create a client-side AngularJS Controller. Create a new folder called “Controllers” under the Script folder as in the following:


Click Add and copy the following code below within your heroesController.js file:

(function () {
    'use strict';

        .controller('heroesController', heroesController);

    heroesController.$inject = ['$scope','Heroes'];

    function heroesController($scope, Heroes) {
        $scope.Heroes = Heroes.query();

The code above depends on the Heroes service that supplies the list of heroes. The Heroes service is passed to the controller using dependency injection (DI). The $inject() method call enables DI to work. The Heroes service is passed as the second parameter to the heroesController() function.

Adding the Heroes Service

We will use an AngularJS Heroes service to interact with our data via Web API. Now add a new folder called “Services” within the Script folder. Right click on the Services folder and select Add > New Item. From the dialog select AngularJS Factory and name it as “heroesService.js” as in the following:

Now click Add and then replace the generated default code with the following:

(function () {
    'use strict';

    var heroesService = angular.module('heroesService', ['ngResource']);
    heroesService.factory('Heroes', ['$resource',
        function ($resource) {
            return $resource('/api/heroes', {}, {
                query: { method: 'GET', params: {}, isArray: true}

The code above basically returns a list of heroes from the Web API action. The $resource object performs an AJAX request using a RESTful pattern. The heroesService is associated with the /api/heroes route on the server. This means that when you perform a query against the service from your client-side code, the Web API HeroesController is invoked to return a list of heroes.

Adding an AngularJS Template

Let’s add an AngularJS template for displaying the list of heroes. To do this we will need an HTML page to render in the browser. In the wwwroot folder add a new HTML page and name it as “index” for simplicity. Your application structure should now look like this:

The wwwroot folder is a special folder in your application. The purpose is that the wwwroor folder should contain all contents of your website such as HTML files and images needed for your website.

You should not place any of your source code within the wwwroot folder. Instead source codes such as MVC controllers’ source, model classes and unminified JavaScript and LESS files should be placed outside of the wwwroot folder.

Now replace the content of index.html with the following:

<!DOCTYPE html>  
<html ng-app="heroesApp"> 
    <meta charset="utf-8" />
    <title>DOTA 2 Heroes</title>
    <script src="//"></script>
    <script src="//"></script>
    <script src="app.js"></script>
<body ng-cloak> 
    <div ng-controller="heroesController">
        <h1>DOTA Heroes</h1>
                <tr ng-repeat="hero in Heroes">

There are several things to point out from the markup above: 
The html element is embedded with the ng-app directive. This directive associates the heroesApp with the HTML file.

In the script section, you will notice that I use Google CDN for referencing AngularJS and related libraries. Besides being lazy, it’s my intent to use CDN for referencing standard libraries such as jQuery, AngularJS and Bootstrap to boost application performance. If you don’t want to use CDN then you can always install AngularJS packages using Bower.

The body element is embedded with the ng-cloak directive. This directive hides an AngularJS template until the data has been loaded in the page. 
The div element within the body block is embedded with the ng-controller directive. This directive associates the heroesController and renders the data within the div element.

Finally, the ng-repeat directive is added to the tr element of the table. This will create row for each data that retrieved from the server.


Here’s the output below when running the page and navigating to index.html:

That’s it! It is more fun to play DOTA!


European ASP.NET MVC 5 Hosting - UK :: Using Bootstrap 3 in ASP.NET MVC 5

clock October 21, 2014 10:00 by author Scott

In this article, we will describe about ASP.NET MVC 5 uses Bootstrap 3 as the CSS framework. You can check our last article about mvc 5 scaffolding.

Get Started with ASP.NET MVC 5

When you create a new ASP.NET MVC 5 Web Application in Visual Studio 2013 it is using Bootstrap 3 as its default CSS Framework. You get the pleasure of the responsive navigation and website along with all the typography and other bells and whistles you expect from Bootstrap 3.

Inside the ASP.NET MVC 5 Website Template you will find the bootstrap.css and bootstrap.min.css stylesheets as well as the bootstrap.js and bootstrap.min.js scripts. The _Layout.cshtml view and other views are marked up appropriately using the CSS selectors in Bootstrap 3.

ASP.NET MVC 5 Bootstrap

By default, the ASP.NET MVC Website Template uses a couple of bundles that use both Bootstrap 3 CSS as well as Modernizr. Check out the Layout.cshtml view to see the use of two of the bundles.


You will find these bundles configured in the BundleConfig.cs file in App_Start.

  bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(

.Add(new StyleBundle("~/Content/css").Include(

And, of course, the CSS selectors and markup in the new ASP.NET MVC 5 Views are based on Bootstrap 3.

That’s only brief tutorial about ASP.NET MVC 5. We will be back with new tutorial again.



FREE ASP.NET MVC 5 Cloud Hosting Belgium - :: About DataAnnotations, MVC and LINQ To Entities

clock May 6, 2014 07:18 by author Peter

In this blog I will be covering some useful features called DataAnnotations which one can use when using LINQ To Entities, together with ASP.NET MVC 5 Hosting. The outcomes of this blog are

  1. Understand and learn how you can create DataAnnotations on your LINQ To Entities generated model
  2. Understand how these annotations link with MVC Views which are then used to modify database data
  3. Understand how validators are then utilized automatically by ASP.NET following the annotations you create

The prerequisites of this blog are

  1. Have some understanding of LINQ To Entities
  2. Have some understanding of MVC and how you can create records using ASP.NET MVC
  3. Have SQL Server Express installed and have a database containing a Products table.

Whenever you create an ASP.NET MVC Template Project using Visual Studio an AccountModel inside the Models folder will be automatically generated. If you open this class you will note that there are some very useful properties which ASP.NET MVC uses to validate data inputted by the user. Let’s take a simple example.

public class LoginModel
 [Display(Name = "User name")]
 public string UserName { get; set; }
 [Display(Name = "Password")]
 public string Password { get; set; }
[Display(Name = "Remember me?")]
 public bool RememberMe { get; set; }

If you examine the above code you will note that on some specific fields there are what so called DataAnnotations. These DataAnnotations are
Display (line 4,9 and 12)
DataType (line 8)
Required (line 3 and 7)

What are these DataAnnotations and why are they used? These DataAnnotations basically give MVC some extra information on what you expect from the user when inputting data in an MVC View. For example, the Required DataAnnotation basically ensures that the specific field cannot be left empty. That would mean that a user would not be allowed to leave the field empty when inputting data. Thus, in the example shown above, the Username and Password fields are both required.The Display DataAnnotation, on the other hand, is used so that the label associated with the field, when displayed in an ASP.NET MVC View, will display the relevant Display information.

The DataType DataAnnotation will provide information on the DataType of that specific field. So for example, the Password field is in our case a Password field. This means that whenever you will be creating a View which accepts a LoginModel class, the Password field will be displayed as an HTML Input Type = password field.

The example which the ASP.NET MVC template project is very useful to let use understand how DataAnnotations can be used. However, what happens when you are using LINQ To Entities and you would have your classes already specified in your model. How can you use these very useful DataAnnotations and apply them to your LINQ To Entities model?

Basically my main aim is not to create DataAnnotations and apply them on a LINQ To Entities model which we have created in this blog. Thus, from now on I will assume that you have a LINQ To Entities class named Product which basically stores products information.

The first thing you will have to do is to create a partial class with the same name as your LINQ To Entities class. So ,in our example we will name our partial class Product. We would then create another class which will contain the MetaData containing all the fields in our LINQ To Entities Product model which we would like to apply DataAnnotations on. This code is shown underneath.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.DataAnnotations;
namespace MVCForBlog.Models
 public partial class Product
public class ProductMetaData
 [Required(ErrorMessage = "Product Name is required")]
 [Display(Name="Product Name")]
 [DataType( System.ComponentModel.DataAnnotations.DataType.Text)]
 public string ProductName { get; set; }
 [Required(ErrorMessage = "Product Description is required")]
 [DataType( System.ComponentModel.DataAnnotations.DataType.MultilineText)]
 [Display(Name = "Product Description")]
 public string ProductDescription { get; set; }

Before I go into the detail of what the above code does I will have to make some points very clear
To use DataAnnotations you should Add A Reference to the System.ComponentModel if this has not already been added
You should ensure that the partial class is in the SAME namespace as your LINQ To Entities model. THIS IS CRITICAL TO MAKE ANNOTATIONS WORK AS EXPECTED.
The fields you create in your class should have the SAME name as the field name specified in the LINQ To Entities model.

If you investigate the code listed you will note the following
From line 8 to line 11 we are creating a partial class with the same name as the class found in our LINQ To Entities model. We are then specifying that it will be using the MetaData created in a separate class named ProductMetaData

The ProductName field specified in line 17 has several data annotations applied. These include Required, which means that the user would not be able to leave the field empty, DisplayName which means that the field which will be displayed near the textbox will be shown as Product Name, and finally DataType which basically specifies what type of data the user should be inputting. In our case the ProductName is a string and thus we are specifying Text as the DataType.

The ProductDescription found in line 22, has the same DataAnnotations as in the previous field. However the DataType for this field is MultiLine text. Thus when this field will be displayed in an ASP.NET MVC View a TextArea will be shown.

Now let’s see how these annotations will affect the ASP.NET MVC View which will be used to create a new product to our database.

Create an ASP.NET MVC View which will create a new product to the database as shown in Figure 1. You will note that when you run your application and try to create a new product, the fields and GUI elements which will be created will reflect the DataAnnotations specified.

European Cloud ASP.NET MVC Hosting - Spain :: Pipeline in ASP.NET MVC

clock April 22, 2014 09:49 by author Scott

In this article, I will write simple tutorial about detail pipeline of ASP.NET MVC.


Routing is the first step in ASP.NET MVC pipeline. typically, it is a pattern matching system that matches the incoming request to the registered URL patterns in the Route Table.

The UrlRoutingModule(System.Web.Routing.UrlRoutingModule) is a class which matches an incoming HTTP request to a registered route pattern in the RouteTable(System.Web.Routing.RouteTable).

When ASP.NET MVC application starts at first time, it registers one or more patterns to the RouteTable to tell the routing system what to do with any requests that match these patterns. An application has only one RouteTable and this is setup in the Application_Start event of Global.asax of the application.

public class RouteConfig
   public static void RegisterRoutes(RouteCollection routes)

   name: "Default",
   url: "{controller}/{action}/{id}",
   defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }

protected void Application_Start()
   //Other code is removed for clarity

When the UrlRoutingModule finds a matching route within RouteCollection (RouteTable.Routes), it retrieves the IRouteHandler(System.Web.Mvc.IRouteHandler) instance(default is System.Web.MvcRouteHandler) for that route. From the route handler, the module gets an IHttpHandler(System.Web.IHttpHandler) instance(default is System.Web.MvcHandler).

public interface IrouteHandler
   IHttpHandler GetHttpHandler(RequestContext requestContext);

Controller Initialization

The MvcHandler initiates the real processing inside ASP.NET MVC pipeline by using ProcessRequest method. This method uses the IControllerFactory instance (default is System.Web.Mvc.DefaultControllerFactory) to create corresponding controller.

protected internal virtual void ProcessRequest(HttpContextBase httpContext)
   SecurityUtil.ProcessInApplicationTrust(delegate {
   IController controller;
   IControllerFactory factory;
   this.ProcessRequestInit(httpContext, out controller, out factory);

Action Execution

1. When the controller is initialized, the controller calls its own InvokeAction() method by passing the details of the chosen action method. This is handled by the IActionInvoker.

public virtual bool InvokeAction(ControllerContext controllerContext, string actionName)

2. After chosen of appropriate action method, model binders(default is System.Web.Mvc.DefaultModelBinder) retrieves the data from incoming HTTP request and do the data type conversion, data validation such as required or date format etc. and also take care of input values mapping to that action method parameters.

3. Authentication Filter was introduced with ASP.NET MVC5 that run prior to authorization filter. It is used to authenticate a user. Authentication filter process user credentials in the request and provide a corresponding principal. Prior to ASP.NET MVC5, you use authorization filter for authentication and authorization to a user.

By default, Authenticate attribute is used to perform Authentication. You can easily create your own custom authentication filter by implementing IAuthenticationFilter.

4. Authorization filter allow you to perform authorization process for an authenticated user. For example, Role based authorization for users to access resources.

By default, Authorize attribute is used to perform authorization. You can also make your own custom authorization filter by implementing IAuthorizationFilter.

5. Action filters are executed before(OnActionExecuting) and after(OnActionExecuted) an action is executed. IActionFilter interface provides you two methods OnActionExecuting and OnActionExecuted methods which will be executed before and after an action gets executed respectively. You can also make your own custom ActionFilters filter by implementing IActionFilter.

6. When action is executed, it process the user inputs with the help of model (Business Model or Data Model) and prepare Action Result.

Result Execution

1. Result filters are executed before(OnResultnExecuting) and after(OnResultExecuted) the ActionResult is executed. IResultFilter interface provides you two methods OnResultExecuting and OnResultExecuted methods which will be executed before and after an ActionResult gets executed respectively. You can also make your own custom ResultFilters filter by implementing IResultFilter.

2. Action Result is prepared by performing operations on user inputs with the help of BAL or DAL. The Action Result type can be ViewResult, PartialViewResult, RedirectToRouteResult, RedirectResult, ContentResult, JsonResult, FileResult and EmptyResult.

3. Various Result type provided by the ASP.NET MVC can be categorized into two category- ViewResult type and NonViewResult type. The Result type which renders and returns an HTML page to the browser, falls into ViewResult category and other result type which returns only data either in text format, binary format or a JSON format, falls into NonViewResult category.

View Initialization and Rendering

1. ViewResult type i.e. view and partial view are represented by IView(System.Web.Mvc.IView) interface and rendered by the appropriate View Engine.

public interface Iview
void Render(ViewContext viewContext, TextWriter writer);

2. This process is handled by IViewEngine(System.Web.Mvc.IViewEngine) interface of the view engine. By default ASP.NET MVC provides WebForm and Razor view engines. You can also create your custom engine by using IViewEngine interface and can registered your custom view engine in to your Asp.Net MVC application as shown below:

protected void Application_Start()
//Remove All View Engine including Webform and Razor
   //Register Your Custom View Engine
   ViewEngines.Engines.Add(new CustomViewEngine());
   //Other code is removed for clarity

3. Html Helpers are used to write input fields, create links based on the routes, AJAX-enabled forms, links and much more. Html Helpers are extension methods of the HtmlHelper class and can be further extended very easily. In more complex scenario, it might render a form with client side validation with the help of JavaScript or jQuery.

Free ASP.NET 5 MVC Belgium Hosting - :: Implementing Validation Mechanism in ASP.NET MVC

clock April 16, 2014 07:17 by author Peter

In this article I will walk you through the steps of implementing validation in the ASP.NET 5 MVC project using jquery.validate.unobtrusive.js

What is Unobtrusive JavaScript?

Unobtrusive JavaScript is the best practices to separate the JavaScript code from presentation or html.

For example
<input type=”button”
onclick=”alert(‘hello world’)“

The above code is obtrusive as we have called the JavaScript alert method within the html control’s input tag. In order to make this unobtrusive we can create a separate JavaScript file and with the help of jQuery we can register a click event for this button like this.

$(document).ready(function () {
$(‘#btn’).click(function (e) {
    alert(‘hello world’);

For validation there is a JavaScript named jquery.validate.unobtrusive.js which can automatically attach validation with all the input controls that you have in your html file. But those controls should have data-val attribute to true. Otherwise the validation for that particular control does not applied. By default, when we use these methods in our code, depending on the data annotation attributes we have used in our Model it automatically applies the validation at the time of rendering the html control.

For example. If our model is:

Person : Message
[GridColumn("Id", true)]
int Id { set; get; }
[GridColumn("Name", false)]
[StringLength(10, ErrorMessage="Length cannot exceed to 10 character")]
string Name { set; get; }

In ASP.Net MVC we can associate a model while adding a view and in that view we can call HTML helper functions like this
@Html.EditorFor(model => model.Name)

This will generates an html as follows

<input data-val=”true” data-val-length=”Length cannot exceed to 10 character” data-val-length-max=”10″ data-val-required=”The Name field is required.” id=”Name” name=”Name” type=”text” value=”Ovais” />

1. You can see that depending on the model it has automatically added the data-val-* properties in the html. You have to add a jquery.validation.unobtrusive.js in your project.

2. Then add the file path in the bundle like this:


3. Then add the script reference in the page as within the script section like this.

@section scripts{


4. Make sure you have controls place inside a form.

Handling validation in AJAX calls

When using server side post back in ASP.Net MVC validation works smooth. But for example if you want to invoke some AJAXified request on any button click and wanted to know if the form is validated or not you can add a code like this.

$(‘#Save’).click(function (e) {
var $val = $(this).parents(‘form’);
if (!($val.valid()))
else alert(‘form have no errors’);

European ASP.NET MVC 5 Hosting - Nederland :: How to Fix SimpleSecurity Error when Upgrading from MVC 4 to MVC 5

clock February 28, 2014 06:56 by author Scott

You will face this weird issue when you upgrade SimpleSecurity from MVC 4 to MVC 5 and this is an issue that you’ll see:

Attempt by security transparent method 'WebMatrix.WebData.PreApplicationStartCode.Start()' to access security critical method 'System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)' failed.

I did some research and found that others were having the same issue. Well it turns out I did not follow the instructions exactly.  Here is one note in the instructions I did not pay close attention to.

: Microsoft-Web-Helpers has been replaced  with Microsoft.AspNet.WebHelpers. You should remove the old package first,  and then install the newer package.

I opened up the NuGet Package Manager and installed the package Microsoft.AspNet.WebHelpers and things started to work.  Note that when you create a new MVC 5 application and try to incorporate SimpleSecurity or SimpleMembership you will hit the same issue because Microsoft.AspNet.WebHelpers  is not installed by default.  It has to be present for SimpleMembership to run correctly.

I verified that all of the features in the reference application are working correctly after the upgrade.  Even the generation of the emails using Postal worked, which I was not sure of because of the upgrade of Razor as well.

One change I needed to make to the SimpleSecurity assembly was to remove the filters AuthorizeAttribute and BasicAuthorizeAttribute and put them in a separate assembly.  I did this because they are dependent upon MVC and Web API assemblies.  So now there is a version for MVC 4 and another for MVC 5. Please check for SimpleSecurity Project Source Code. Hope it helps
