Web: ASP.NET MVC

Sometimes when performing ajax databinding with the MVC grid you may end up with unexpected result: server error 500. What is even stranger is that server-side binding works as expected with the same data binding code.

[Download the complete final project] We got a customer inquiry today about how to integrate the Telerik Silverlight Upload control within an ASP.NET MVC site. This is quite an interesting scenario, especially with the new Drag and Drop from the file system coming with our Silverlight 4 release in the mid-March. I was not sure what should be done to run the SL upload in the MVC site. This was my first time experience with ASP.NET MVC 2 and it turned out to be a very pleasant and easy one.

Here are the needed steps: Add references to the following assemblies: System.Web.Abstractions System.Web.Routing System.Web.Mvc Telerik.Web.Mvc The first three are usually in the GAC.

Also, you should mock an MVC environment, like this: protected class ControllerMock : Controller { public ControllerMock(NameValueCollection queryString) { foreach (string param in queryString.Keys) ...

As many of you know yesterday ASP.NET MVC 2 RC was released. We did our best to make Telerik Extensions for ASP.NET MVC compatible with that release and I am glad to announce that you can now download the updated bits from here (open source) or here (licensed). Changes There are a few things that changed: We are now producing two dll files – one for ASP.NET MVC 1 and one for ASP.NET MVC 2. The files differ only in their version: For ASP.NET MVC 1 applications you should use Binaries\Mvc1\Telerik.Web.Mvc.dll. Its assembly version ends with 135 (which means MVC v1 .NET...

In this blog post I will demonstrate how to squeeze the most from Telerik Grid for ASP.NET MVC when using Ajax binding. Lets start with a simple grid bound to the Northwind Orders table: View: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<UsingDto.Models.Order>>" %><asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page</asp:Content><asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"><%= Html.Telerik().Grid(Model) .Name("Grid") .Columns(columns => { columns.Add(o => o.OrderID).Width(100); columns.Add(o => o.Customer.ContactName).Width(200); ...
