I just installed the Q3 silverlight controls.  Now, my RadTabControl does not automatically select a tab when it is clicked on.  If I capture the MouseLeftButtonDown event, and set the IsSelected property of the sender to true, it works like it is suppose to, but before this happened automatically.  Is this by design, or do I need to do something different to have the tabs automatically selected when they are clicked on?

Hi Sarkis Matossian,

This is quite unexpected!

Can you confirm that there is no overlay (a transparent visual object) over the tabs?

Are the IsEnabled / IsHitTestVisible properties both true for the control and the items?

Are there other visual items in the headers of the tabs, apart from a TextBlock?

Are you using a custom ControlTemplate? If you are, make sure that there is an element in the template called  "wrapper" and that it is the root Grid of ControlTemplate or something similar.

I created a TabControl with the 8.12 version of the controls and I could not reproduce the issue. Anything else that could help us identify what may be going wrong in your case is welcome.

naming the root element of the ControlTemplate "wrapper" solved the issue.
