This is the first part of a series of posts demonstrating common scenarios of RadTreeView control. I’ll be covering both WPF and Silverlight. One of the most common scenarios for our customers is populating the RadTreeView with data. In WPF data binding is one of the most powerful concepts. Data binding the Treeview can be done in several ways.

Instead of including all our controls into one big assembly, we decided to group them into several smaller ones. This will reduce the size of the XAP file when you are not using all the controls in the suite. We came up with the following list of assemblies:

• Telerik.Windows.UI.dll
• Telerik.Windows.Controls.Navigation.dll
• Telerik.Windows.Controls.Input.dll
• Telerik.Windows.Controls.Web.dll

Apart from this list there will be assemblies that hold the themes of the controls - ...

My colleague Hristo Deshev just announced the availability of Telerik RadControls for WPF Beta2. This is a very important release not only because it brings so many new features and controls for WPF, but because this is our first release that includes the Silverlight and WPF controls under a single distributable.

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.

What does this mean to you as a ...

Do you use Fiddler to inspect the HTTP traffic?

You may be faced with the following problem: since we started using the beta of the IE7 browser we started experiencing problems when monitoring the requests sent to http://localhost or http://127.0.0.1 - the requests were not reported by the Fiddler tool.
