    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'.    
    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.

    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!
