I am getting the same issue with the RadOutlookBar.  Do you have a workaround?

Thanks,
Dmitry

Hello Dmitry,

Unfortunately we cannot offer a workaround for the moment, but we are working on the issue and a fix will be available with the upcoming Q3 2010 official release due in the middle of November.

I hope this timeframe is acceptable for you.

Best wishes,

For those looking for a workaround, I noticed this when the tabControl has a selectionChanged event. Removing the event from the xaml fixed the designer issue for me.
