    RadTreeView for ASP.NET Ajax - Binding to LinqDataSource

    Since the Q2 2008 SP1 release RadTreeView, RadMenu, RadPanelBar and RadTabStrip support hierarchical databinding to the LinqDataSource control. In this blog post I will demonstrate how to do this with RadTreeView (the steps are identical for the aforementioned controls). Create a new Web Site in Visual Studio 2008 and copy the Northwind database in your App_Data folder Add a new "Linq to SQL classes" item named "Northwind.dbml"

    RadTreeView for ASP.NET Ajax - Optimizing Load On Demand performance

    In a previous blog post I mentioned that you should use WebService load on demand in order to squeeze the most performance from RadTreeView.

We start with a simple page containing only a single RadTreeView control with one root node. The testing environment is: Visual Studio 2008 SP1 Intel Core 2 Duo E6550 @ 2.33GHz.

    RadControls for Silverlight and WPF

    My colleague Hristo Deshev just announced the availability of Telerik RadControls for WPF Beta2.

For this first release we ported just a few Silverlight controls for WPF (namely TreeView, PanelBar, Calendar, DatePicker, Slider, ProgressBar and NumericUpDown), but in the long run almost all Silverlight controls that are applicable in a desktop scenario will be included in the WPF suite.
