Earlier this week, I ran across a forum post asking about how one would go about creating multiple RadListBoxes that supported multi-item drag and drop. This sounded like a fun challenge, so I decided to take it on. Referencing an earlier forum post that described single-item drag and drop, I came up with the following solution.

Calling DoDragDrop() immediately changes the mouse pointer and readies the RadListBox for the drag-and-drop operation. Originally, I had tried calling this function in the MouseDown event, but this lead to unpredictable clunky behavior due to the fact that DoDragDrop() was getting called before I had the chance to ...

Along with the Service Pack of RadControls for Silverlight Q2 we released an update of the free test automation solution, the WebAii Testing Framework. There are additions, fixes and improvements in all the components including the core WebAii, WebAii RadControls for Silverlight and ASP.NET AJAX. With this post I’d like to bring your attention to the latest addition to our Silverlight controls wrappers – the RadHtmlPlaceholder one.

As you probably know, the control itself is a pretty useful component part of the RadControls for Silverlight suite. RadHtmlPlaceholder allows you to host any HTML content in your Silverlight application ...

Hello everyone, and welcome to the third tutorial in my series of tutorials about the Telerik CAB Enabling Kit. Over the next two weeks, I will be covering the two workspaces provided with the TCEK. This week, we will learn how to use the RadTabWorkspace. I will be using the completed project from tutorial 2 as the base for this project. If you have not completed the second tutorial, I suggest doing so before completing this tutorial. You can find it here. Otherwise, click here to download the source code that we will be using, fire up visual studio, ...

You are probably aware that one of the great new features coming up with the WebUI Test Studio v2.0 is the Silverlight automation support! Yes, that’s correct – you will be able to record all your tests against any Silverlight application as easy as you currently generate the ASP.NET tests. As you might expect we are also working on the RadControls for Silverlight translators. They will let you automate the RadControls for Silverlight components out-of-the-box.

I’ve just captured a snapshot of the RadTreeView translator providing some helpful verification tasks. It is taken from the live demo here.

While organizing ...

Hello everyone, and welcome to the second tutorial in my series of tutorials about the Telerik CAB Enabling Kit (TCEK). This week I will be talking about the UIExtensionSites supported in the TCEK. The TCEK comes with a number of UI Adapters that provide support for the following controls.

• RadMenu
• RadToolStrip
• RadPanelBar
• RadTreeView

These controls are supported through the registration of custom Adapter Factories and Command Adapters. Adapter Factories simplify the task of creating custom UI Adapters for individual controls. Command Adapters allow you to add invokers and/or set command status on specific controls. In the last tutorial, we created ...
