I have the same question as Yelong and the first reply from Hristo, suggesting to comment out some storyboard animations, is exactly what I needed to do. I do have the latest Silverlight RadControls installed (Q3 2010 SP1) and manage to get it working.
However, my Silverlight application is using a Theme set in the App.xaml.cs file:
I notice in runtime that my RadPanelBarItem renders the "Office_Black" look and feel which is the styles present in the modified style resources. I don't have any other Telerik control template customizations as I rely on the StyleManager to theme all controls for me.
How do I edit the RadPanelBarItem template to disable the mouse over events as well as ensure that the control will render according to my App.xaml.cs theme setting?
