Hello Sandeep,

This is an issue with the current Microsoft Silverlight runtime. Try adding the RadWindow control as a child of a panel, so the Radwindow is part of the visual tree. This should fix the problem. Please let us know if the problem persist.

I tried your suggestion but still did not fix the issue.  I have latest Telerik controls and I am using a Telerik Window which contains a custom user control with a TreeView and Calendar control.  The Calendar control works without any issue.  The TreeView works without any issues when expanding the tree node but when selecting it blows chunks.... the error is as follows:  Please advise.
