[Solved] AJAX Databinding with ASP.Net MVC 3 Razor - HTTP 500 Popup

[Missing User]

Hi,

I am trying to convert my Client Index View to use a Telerik Grid to display the clients. I have been reading through some examples and I am following the following Demo:
http://demos.telerik.com/aspnet-mvc/razor/grid/ajaxbinding

However when I am trying to test my code I get a popup as soon as grid databinds, saying: "Error! The requested URL returned 500 -error"

If I debug the Action in the controller all seem fine untill I step out of the Action then the debugger tries to locate a file called "GridActionAttribute.cs" in the following directory:
"Locating source for 'f:\114\Griffin\Trunk Full\Sources\Source\Telerik.Web.Mvc\UI\Grid\GridActionAttribute.cs"

Here is my View:

@model IEnumerable<MUMSUtilities.Client>
@using Telerik.Web.Mvc.UI
@{
    ViewBag.Title = "Client Index";
}

<h2>Client Index</h2>

<p>
    @Html.ActionLink("Create New", "Create")
</p>

@(Html.Telerik().Grid<MUMSUtilities.Client>("Clients")
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(c => c.ClientName);
    })
    .DataBinding(dataBinding => dataBinding.Ajax().Select("AjaxBinding", "Client"))
    .Pageable()
    .Sortable()
    .Scrollable()
    .Groupable()
    .Filterable())

And my Controller Action:

[GridAction]
public ActionResult AjaxBinding()
{
    var clients = db.Clients.ToList();
    return View(new GridModel<Client> { Data = clients, Total = clients.Count });
}

Any idea why the Databind is not working correctly?

Kind Regards,
Paul

Try remove the "Clients":

@(Html.Telerik().Grid<MUMSUtilities.Client>()
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(c => c.ClientName);
    })
    .DataBinding(dataBinding => dataBinding.Ajax().Select("AjaxBinding", "Client"))
    .Pageable()
    .Sortable()
    .Scrollable()
    .Groupable()
    .Filterable())

You should also have a look at your firebug / fiddler to see the server response. The response should be a normal ASP.NET error page and should display the error that is happening.

And instead of using Telerik's GridModel, it is sufficient to just return JSON data:

[GridAction]
public ActionResult AjaxBinding()
{
    var clients = db.Clients.ToList();
    return Json(clients);
}
