Hello,

I'm receiving the following exception when pinning a pane:

Line: 56
Error: Unhandled Error in Silverlight Application
Code: 2531   
Category: ParserError      
Message: Failed to assign to property 'System.Windows.Controls.Primitives.Popup.Child'.    
File:     
Line: 202    
Position: 31
    

This only occurs after I've loaded RadDocking using LoadLayout from Xml that contains a RadPane that is unpinned.

So to reiterate, you need to load RadDocking with a layout that contains a pane that is unpinned. When you attempt to pin that pane the exception is thrown.

Can you replicate this your end?

I am using build Silverlight_4_2010_1_0430.

Regards,

James.

Hi James,

 I couldn't reproduce this problem. Could you please open a support ticket and provide us with a sample project that reproduces the issue? This would be very helpful for find out what the problem is.

Best wishes,

No problem, I found what was causing this and it looks like a bug in Silverlight when displaying a Pop Up within a Pop Up. Setting IsOpen in Xaml to True caused the exception, but if I set IsOpen during the Loaded event handler then all is fine. Very strange!
