    How to Databind RadTreeView in WPF

    Download the source code of the samples here. 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. In this post I’ll explain the most common scenarios – binding to an XML file, binding to a Collection, and a more advanced sample – data binding using grouping and CollectionViewSource.

    New gaud for the 3-Dimensional WPF RadChart

    Last time I wrote about Labels in 3D, but it turned out to be more of a Step-By-Step How-To. This time the blog will be short and up to the point - our RadChart for WPF has a new shiny primitive, which is ... ta-daaaaa ... a 3-Dimensional Rounded Bar/Box.   Well, we are not the first to introduce such a primitive. It is, of course, easy to create rounded box model in 3D Studio Max, Maya or any other 3D-modeling tool (as other component vendors did for you), but that approach does not allow easy customization - each time you...

    RadControls for WinForms gaining more speed

    …Or how you should manage predefined themes in Q2 2008 As mentioned previously, RadControls for WinForms is the only WinForms suite which provides WPF-like effects on the classic Windows Forms platform. This has its challenges, because the Windows Forms platform was not build with such rich visualization in mind. For example, performance suffers if too many elements are animated on the form; the form/application start up time increases with too many visual elements on the form, etc. It is our job to try and find ways to keep these times at a minimum, but keep the same rich functionality and dazzling...

    WPF: The Static Nature of Dependency Properties

    With dependency properties being so heavily used across the WPF platform, there is a good chance that sooner or later you will get bitten by this issue my colleague Hristo Deshev and I were debugging not long ago. Some heads-up can't really hurt anybody so here it is;). We will declare a simple class Foo with a single collection dependency property (note that this is a reference type). We will also supply our brand new property with a default value through the convenient DependecyProperty.Register(...) method: Let us put our class to the test by creating two Foo instances and adding a single item...
