We are experiencing the same issue.  It appears to be the RadTabControl.  We created a new Telerik Silverlight template project, bulit, and then tried to add the RadTabControl to the project and received HRESULT:0x80004005(E_FAIL).

Our existing project which already had the tab control would not allow us to view the Events tab of the Properties without throwing the error that Stephan mentioned.

Hello FRITZ,

@ Stefane. We logged this issue in our PITS where you can track its status. We'll do our best to have this fixed for some of the internal builds in the next weeks. Please accept our apologies for the inconvenience caused.
@Fritz. The events of the properties won't appear if you have defined a selection event handler in xaml which is related to the mentioned issue. Do you use SelectionChanged or PreviewSelectionChanged?
When does H_Result error occur? Could you please elaborate more or send us a runnable sample if your first issue has nothing to do with the designer issue ? Thank you for your cooperation.

Hi FRITZ,

This issue is fixed and you can use the official  Q1 SP1 version of RadControls 0419. Let us know if you need further assistance.
