Hi Deepak,
Unfortunately this feature is not available yet.
We will implement it for the TabControl used in docking:
http://demos.telerik.com/silverlight/#Docking/FirstLook
but unfortunately I cannot say with certainty whether it will be there for the Q1 release.
Thanks for your feedback, it gives this feature a higher priority.
Greetings,
Miroslav
