ASP.NET MVC 6 Hosting UK - HostForLIFE.eu :: How to Get the Values from HTTP Query String Variables in View in ASP.NET MVC 6 ?

clock January 29, 2015 07:21 by author Peter

This method can be utilized as a part of any perspective however it is prescribed to verify your ViewModel contains all essential data. We are going to utilize this methodology as a part of design page, as regularly layout page does not have any model(it can have however then it may get exceptionally muddled and by and by I think for enormous tasks it could be extra constraint).

Consider a circumstance in which you are occupied with values for variables from HTTP request.
http://localhost:49853/Home/Index?searchType=global

In above address we are passing variable searchType. How about we accept that searchType. can have 2 separate values - local and global.
Main CSS file:
#mainNav.global {
  background: #404939; }
  #mainNav.global nav.nav {
    background: none; }
    #mainNav.global nav.nav .top {
      background: #404939; }
    #mainNav.global nav.nav a:hover, #mainNav nav.nav a.active {
      background-color: #7dc243; }     
      #mainNav.local
      {
          background: #3C7987; }
        #mainNav.localnav.nav {
                  background: none; }
        #mainNav.local nav.nav .top {
                          background: #3C7987; }
        #mainNav.local nav.nav a:hover, #mainNav nav.nav a.active {
                        background-color: #7FDCFF; }


In layout page in _Layout file header section:
<header>
        <div class="content-wrapper">
            <div class="float-left">
                <p class="site-title">@Html.ActionLink("your logo here", "Index", "Home")</p>
            </div>
            <div class="float-right">
                <section id="login">
                    @Html.Partial("_LoginPartial")
                </section>
                @{
                    string searchClass = "global";
                    if (HttpContext.Current.Request.Params["searchType"] == "local")
                    {
                        searchClass = "local";
                    }
                }
                <div id="mainNav" [email protected]>
                    <nav class="nav" data-nav>
                        <ul>
                  @using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "searchForm" }))
                            {
                                @Html.ActionLink("Global","Index","Home", new { searchType= "global" }, null)
                                @Html.ActionLink("Local","Index", "Home", new { searchType = "local" }, null)
                                <input type="search" name="searchMode" value="" placeholder="Search...">
                                <input type="submit" name="submitBtn" value="Search">
                            }
                        </ul>
                    </nav>
                </div>
               <nav>
                    <ul id="menu">
                        <li>@Html.ActionLink("Home", "Index", "Home")</li>
                        <li>@Html.ActionLink("About", "About", "Home")</li>
                        <li>@Html.ActionLink("Contact", "Contact", "Home")</li>
                    </ul>
               </nav>
            </div>
        </div>
    </header>

Now, we aregoing to toggle class name for navigation bar. If we are in global searchType background color is #7dc243, in local searchType 7FDCFF.

If you are in global searchType your address is :
http://localhost:49853/?searchType=global

In local :
http://localhost:49853/?searchType=local

ASP.NET MVC 6 Hosting UK - HostForLIFE.eu :: Changing image opacity & Zoom on mouseover using jQuery in ASP.NET MVC

clock January 23, 2015 12:20 by author Peter

With this post, I will explain you about changing image opacity & zoom on mouseover with jQuery in ASP.NET MVC. First step, write the following code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>How to change image opacity and Zoom on mouseover using jQuery</title>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#imgSample").css("opacity", "0.5");
            $("#img1").hover(function () {
                $(this).css("opacity", "1.0");
                $(this).animate({ width: "400px" }, 'slow');
                $(this).animate({ height: "300px" }, 'slow');
            },
              function () {
                   $(this).css("opacity", "0.5");
                   $(this).animate({ width: "200px" }, 'slow');
                   $(this).animate({ height: "150px" }, 'slow');
               });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
       <img id="imgSample" src="images/NiceImage.jpg" width="200px" height="150px" alt="img" />
        <img id="img1" src="images/NiceImage.jpg" width="200px" height="150px" alt="img" />
    </div>
    </form>
</body>
</html>

And here is the result of the code above.

The Opacity 0.5 shows like the picture below.

ASP.NET MVC 6 Hosting Russia :: Creating Dynamic DropdownList in ASP.NET MVC 6

clock January 22, 2015 05:54 by author Peter

With this short tutorial, I will tell you how to create dynamic DropDownList with ASP.NET MVC 6. First thing you should do is make 2 DB Tables. And here is the example:

1.Designstions
Columns: DesignationID(PK,FK,numeric(6,0),not null)
             Designation (Varchar(50),null)

2.Persons
Columns: PersonID(PK,numeric(6,0),not null)
                 DesignationID(FK,numeric(6,0),not null)


Create The Models:
Designation.cs
{
   public decimal DesignationID { get; set; }
    public string Designation { get; set; }
}


Person.cs
{
    public decimal PersonID{ get; set; }
     [DisplayName("Designation")]
   public decimal DesignationID{ get; set; }
    public virtual  Designation designation { get; set; }
}


PersonController.cs
{
  public class PersonController: Controller
{
     public ActionResult Index()
        {
            var  mamun= db.Persons.Include(t => t.designation );
            return View(mamun.ToList());
        }
 public ActionResult Create()
        {
          ViewBag.DesignstionID= new SelectList(db.Designstions, "DesignstionID", "Designstion");
            return View();
        }
  public ActionResult Edit(decimal id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Person person = db.Persons.Find(id);
            if (tblsalesperson == null)
            {
                return HttpNotFound();
            }
         ViewBag.DesignstionID= new SelectList(db.Designstions, "DesignstionID", "Designstion",person.DesignstionID);
                   return View(person);
        }
}
}

Next step, create.cshtml & Edit.cshtml:
<div class="form-group">
                @Html.Label("Designation", new { @class = "control-label col-md-2" })
                <div class="col-md-10">
                    @Html.DropDownList("DesignstionID")
                    @Html.ValidationMessageFor(model => model.DesignstionID)
                </div>
            </div>

I am using this following code to Add CSS class  'dropdownList' :
@Html.DropDownList("DesignstionID", (IEnumerable<SelectListItem>)ViewBag.DesignstionID, new { @class = "dropdownList" })  Instead Of that.

Index:  
@foreach (var item in Model)
{
    <td>
                    @Html.DisplayFor(modelItem => item.Designation.Designation)     
  </td>
}

ASP.NET MVC 6 Hosting Germany - HostForLIFE.eu :: How to Create Random Authorization code in c# in ASP.NET MVC ?

clock December 19, 2014 06:19 by author Peter

Now, with this article I am going to create random 15 characters long authorization number in ASP.NET MVC 6. This can be used for several completely different purposes in your MVC application like unique barcodes, authorization codes etc. to make thinks more fascinating we are getting to force the method to place letter before and after random code. GenerateLetter method is responsible to provide us only letter. I used this code based on small tutorial.

Controller
public char GenerateLetter()
        {
            Random randomNumber = new Random();
            int number = randomNumber.Next(0, 26);
            char letter = (char)('a' + number);
            return letter;
        }
        public string GenerateAuthCode()
        {
            bool codeExists = false;
            string code = GenerateLetter().ToString();
            do
            {
                code += Guid.NewGuid().ToString("N").Substring(0, 13);
                code += GenerateLetter().ToString();
                YourDBContext dbContext = new YourDBContext();
var Exists = dbContext.products.FirstOrDefault(m => m.barcode ==   code);
                codeExists = Exists == null? false : true;
            }
            while (codeExists);               
            return code;       
        }

I am calling GenerateLetter method twice before & after random 13 characters code is generated. I also want to make sure that code is always unique so I am calling Database to find if any product already have this barcode, if so my method will repeat whole process.



ASP.NET MVC 6 Hosting Europe - HostForLIFE.eu :: ASP.NET MVC 6 Overview

clock June 16, 2014 13:28 by author Peter

Good News! Microsoft has been released ASP.NET MVC 6 on 12 May 2014 at TechEd North America, as part of ASP.NET vNext, the MVC, Web API, and Web Pages frameworks will be merged into one framework. Microsoft feels that System.Web needs to be removed because it is actually quite expensive. A typical HttpContext object graph can consume 30.000 of memory per request. When working with small JSON-style requests this represents a disproportionately high cost. With ASP.NET MVC 6 new design, the pre-request overhead drops to roughly 2000.

The new ASP.NET MVC 6 assumes you are familiar with either MVC 5 or Web API 2. If not, here is some terminology that is used in ASP.NET MVC. The new framework removes a lot of overlap between the existing MVC and Web API frameworks. It uses a common set of abstractions for routing, action selection, filters, model binding, and so on. You can use the framework to create both UI (HTML) and web APIs.

Features of ASP.NET vNext & ASP.NET MVC 6

  • A controller handles HTTP requests and executes application logic.
  • Actions are methods on a controller that get invoked to handle HTTP requests. The return value from an action is used to construct the HTTP response.
  • Razor syntax is a simple programming syntax for embedding server-based code in a web page.
  • Routing is the mechanism that selects which action to invoke for a particular HTTP request, usually based on the URL path and the HTTP verb.
  • A view is a component that renders HTML. Controllers can use views when the HTTP response contains HTML.
  • ASP.NET vNext includes new cloud-optimized versions of MVC, Web API, Web Pages, SignalR, and Entity Framework.
  • The welcome page is not too interesting, so lets’s enable the app to serve static files.
  • Mono is a Supported Platform. In the past the support story for Mono was essentially “we hope it runs, but if it doesn’t then you need to talk to Xamarin”. Now Microsoft is billing Mono as the official cross-platform CLR for ASP.NET vNext.
  • ASP.NET vNext support true side-by-side deployment. If your application is using cloud-optimized subset of ASP.NET vNext, you can deploy all of your dependencies including the .NET vNext (cloud optimized) by uploading bin to hosting environment.
  • Cross Platform Development. Not only is Microsoft planning for cross-platform deployment, they are also enabling cross-platform development.



ASP.NET MVC 6 Hosting South Africa - HostForLIFE.eu :: How to Create a RSS feed with the new ASP.NET MVC 6

clock June 13, 2014 11:10 by author Peter

Today, we are going to discuss about create RSS feed on ASP.NET MVC 6 Hosting. The RSS classes that we will be describing are available in all types of ASP.NET applications, not only the web-based onces. But we think displaying a blog item on your website is great and relatively simple example of consuming RSS feeds in ASP.NET.

There actually is built-in RSS support in ASP.NET. We have not been aware of that support for some time and occasionally used the third-party library RSS.NET. It turns out that we do not need a separate library any longer. Here is an example MVC controller that refers to the SyndicationFeed and SyndicationItem classes in its Index action method.

using System.Web.Mvc;
using System.ServiceModel.Syndication;
using System.Xml;
using System.Linq;namespace Antrix.Web.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Message = "Welcome to ASP.NET MVC!";
            const string feedUrl =
            "http://yourdomain.com/feeds/posts/default?alt=rss";
           SyndicationFeed feed = null;
           using (XmlReader reader = XmlReader.Create(feedUrl))
            {
                feed = SyndicationFeed.Load(reader);
            }
            if (feed != null)
            {
                SyndicationItem item = feed.Items.First<SyndicationItem>();

                ViewBag.RssItem = item;         
            }
           
             return View();
        }
        public ActionResult About()
        {
            return View();
       }
    }
}

The Index method will reads a feed of the site that you are reading right now. It puts the first item (which we assume represents the last post that has been published) in the ViewBag. Normally we use model classes to refer to data within my MVC views, but we want to keep things simple. We have added code to show the title and summary of the last post, and a link to the full post.

@{
    ViewBag.Title = "Home Page";
}
<h2>@ViewBag.Message</h2>
<p>

    To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>.
</p>
<div>

From our blog:  
<div style="font-weight: bold; padding: 10px">@ViewBag.RssItem.Title.Text</div>
<div style="clear: both; padding: 10px">@Html.Raw(@ViewBag.RssItem.Summary.Text)</div>
<div style="clear: both; padding: 10px"><a href="@ViewBag.RssItem.Links[0].Uri" target="_blank">Show full post</a></div>
</div>

Using the SyndicationFeed and SyndicationItem classes it becomes rather easy to create your own web-based (or Windows-based, if you prefer) RSS reader.
