Hi ,
I've developed a few lines of code with ASP.NET MVC wrappers of Telerik
A Customer Entity with ID , Name , Rate
Entity Framework Code First Context
A Controller with this code :

public ActionResult Index()

{

return View();

}

public ActionResult Customers([DataSourceRequest] DataSourceRequest request)

{

var customers = Context.Customers.ToDataSourceResult(request);

return Json(customers);

}

and a view with this code

@(Html.Kendo().Grid<Customer>()

.Name("CustomersGrid")

.Columns(columns =>

{

columns.Bound(c => c.ID).Groupable(false);

columns.Bound(c => c.FName);

columns.Bound(c => c.LName);

columns.Bound(c => c.Rate);

})

.Groupable()

.Pageable()

.Sortable()

.Scrollable()

.Filterable()

.DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("Customers", "Customer"))

)

when render of view finishes at the end of @HTML.Kendo
I give this exception

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
