Showing loading animation in center of page while making a call to Action method in MVC

Now, use javascript to show it in and hide, when an ajax request starts. 
<script type="text/javascript">
    $(document).ajaxStart(function () {
        $('#spinner').show();
    }).ajaxStop(function () {
        $('#spinner').hide();
    });
</script>


Style the div element to position it on the centre of the browser.
<style>
div#spinner
{
    display: none;
    width:100px;
    height: 100px;
    position: fixed;
    top: 50%;
    left: 50%;
    text-align:center;
    margin-left: -50px;
    margin-top: -100px;
    z-index:2;
    overflow: auto;
}  
</style>


Put the html for the loader in the page.
<div id="spinner">
    <img src="~/Images/googleLarge.gif" alt="Loading..."/>
</div>

MVC 3 AJAX redirecting instead of updating DIV

Finally I tracked it down to two issues.
I realized that if I set UnobtrusiveJavaScriptEnabled to false in my web.config file, everything worked.


A second issue, and one that I suspect others may run into as well, is that I didn’t have a reference to jquery.unobtrusive-ajax.min.js in my master (or child) page.  Since MVC 3 uses UnobtrusiveJavaScript by default, it’s essential that the Javascript files are referenced, otherwise it can break unrelated Javascript, making it obtrusive rather than unobtrusive.  Obviously not the desired effect.
The correct scripts that are required for MVC+AJAX plus UnobtrusiveJavaScript are:

1. <script src="@Url.Content("~/Scripts/jquery-1.4.1.min.js")" type="text/javascript"></script>
2. <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
3. <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
4. <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
5. <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>

Hope this help you.

MVC Force Validation of Hidden Fields

I need to enable the validation of hidden fields using ASP.net MVC3/4 unobtrusive validation.
The reason behind this is a jquery plugin which hides the original input field to show something fancier.
But this disables validation of the field as it becomes hidden.

Finally i found perfect solution.
Now we are able to validate hidden field with following code.

$( document ).ready(function()
{
   var validator = $("#myFormId").data('validator');
   validator.settings.ignore = "";
});

Hope this help you.

Linq to sql: Order by desc, then order by asc?

var query = from person in people
            orderby person.Name descending, person.Age descending
            select person.Name;

is equivalent to:

var query = people.OrderByDescending(person => person.Name)
                  .ThenBy(person => person.Age)
                  .Select(person => person.Name);

ASP.NET MVC ajax.beginform : No parameterless constructor defined for this object

This can also be caused if your Model is using a SelectList, as this has no parameterless constructor:

public class MyViewModel
{
    public SelectList employeeList {get;set;}
}

 You'll need to refactor your model to do it a different way if this is the cause. So using an

IEnumerable<SelectListItem> and writing an extension method that

creates the drop down list with the different property definitions:

public class MyViewModel
{
    public IEnumerable<SelectListItem> employeeList { get; set; }
}

Perfect solution !

Unobtrusive / client side validation doesn't work with Ajax.BeginForm

You need to add those 2 files in your Partial View even if it is already in the Shared/_Layout.cshtml:

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

Or place this in your Partial:

<script type="text/javascript" language=javascript>
    $.validator.unobtrusive.parse(document);
</script>


Perfect solution.

          .DefaultIfEmpty()

How to render a DateTime in a specific format in ASP.NET MVC 3?

How can we plug an ASP.NET MVC into an existing ASP.NET application ?

We can combine ASP.NET MVC into an existing ASP.NET application by following the below procedure:

First of all, you have to add a reference to the following three assemblies to your existing ASP.NET application:

i) System.Web.Routing
ii) System.Web.Abstractions
iii) System.Web.Mvc

The ASP.NET MVC folder should be created after adding these assembly references.
Add the folder Controllers, Views, and Views | Shared to your existing ASP.NET application.
And then you have to do the necessary changes in web.config file.
For this you can refer to the below link:

http://www.packtpub.com/article/mixing-aspnet-webforms-and-aspnet-mvc

asp.net mvc 3 - Converting DateTime format using razor

Tricky solution :

Restrict to numeric id only in mvc routing

Suppose we have defined the following route in our application and you want to restrict the incoming request url with numeric id only. Now let's see how to do it with the help of regular expression.

routes.MapRoute(
 "Default", // Route name
 "{controller}/{action}/{id}", // Route Pattern
 new { controller = "Home", action = "Index", id = 

 UrlParameter.Optional } //Default values for parameters
);

Restrict to numeric id only

routes.MapRoute(
 "Default", // Route name
 "{controller}/{action}/{id}", // Route Pattern
 new { controller = "Home", action = "Index", id = 

 UrlParameter.Optional },//Default values for parameters
 new { id = @"\d+" } //Restriction for id
);

Now for this route, routing engine will consider only those URLs which have only numeric id like as http://abc.com/Admin/Product/1 else it will considers that url is not matched with this route.

Get the url to the virtual root for the current request

Example(1)
Uri requestUri = Context.Request.Url;
string baseUrl = requestUri.Scheme + Uri.SchemeDelimiter + requestUri.Host + (requestUri.IsDefaultPort ? "" : ":" + requestUri.Port);

Example(2)
This can be done much easier with the following code:
string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);

Route data inside a controller

We can access routing data inside a controller using the RouteData object.

public ActionResult Index()
{
   ViewBag.Message = String.Format("{0}---{1}---{2}",
                                    RouteData.Values["controller"],        
                                    RouteData.Values["action"],
                                    RouteData.Values["id"]);
    Return View();
}

Removing the WebForms View Engine in MVC

If Razor is the only view engine you use in an ASP.NET MVC application, then it makes sense to remove the Web Forms view engine and save some cycles. Otherwise, the MVC runtime will go looking for .aspx and .ascx files when it tries to locate a view or template. A small savings, but just 2 lines of code required during application startup.

ViewEngines.Engines.Clear();

ViewEngines.Engines.Add(new RazorViewEngine());
