If you want to filter a column that is data-bound to a custom type, you need to make sure that your custom type meets certain criteria. We will use the type Person as an example. public class Person {     private readonly string name;     private int age;     public string Name     {         get { return this.name; }     }     public int Age     {         get { return this.age; }         set { this.age = value;...

Many applications render data in tables; writing tests for table-based data is a very common task. Unless you approach it with a bit of preparation, it’s also a task that can easily result in you building very brittle tests. Consider the following grid which displays a list of contacts after having taken actions elsewhere in the system. (I’m using a Telerik RadGrid for AJAX in this example, by the way.)

The first release of 2012 is already a fact and even though this Q has been shorter due to the shift in the release dates which Todd Anglin blogged about, we managed to include some long-awaited improvements and new features.

Unless you missed it somehow, last week Microsoft released the public preview of Windows 8 along with the beta of Visual Studio 11. They are both available for download right now and we encourage you to check out the tiled future :). If you already did that and you are still wondering if it's possible to build normal ASP.NET AJAX web applications using the new Win and VS releases, then this blog post will be helpful to you! First of all, a new build of the Telerik's ASP.NET AJAX controls is available in your accounts, specifically targeting Visual Studio 11 beta! The features...

For those of you who are already playing with the Beta version of Visual Studio 11, we have some exciting updates, as well as a bit of a roadmap to share. We have been (and will continue) working very closely with Microsoft to make sure all of our products support the beta.  I am happy to report that most of our products are compatible with the beta and can be downloaded today:  UI Components: RadControls for ASP.NET AJAX RadControls for ASP.NET MVC RadControls for WinForms  Data: Telerik Reporting Telerik OpenAccess ORM - in Fluent scenarios only, get the NuGet package here.  Visual Studio Productivity Plug-ins: Telerik JustTrace Telerik...
