I've just had the opportunity to test upgrading from Silverlight 2 to Silverlight 3, and the Q2 2009 rad controls, and have hit an issue with my existing application.
My iniital screen consists of a RadDocking control, with a RadSplitContainer on the left to provide a menu sidebar, and a DocumentHost on the right, with a RadSplitContainer and RadDocumentPane inside, for content.
When a user selects a menu option, I programatically set the RadDocumentPane.Content to be the relevant user control. However, since moving to SL3 and Q2 2009, I am now presented with the following error message:
"Placing Docking control in another Docking control is not supported in the current version".
As a test, I launched the user controls within a RadWindow, that allowed the controls to be shown, although the context menus for child controls within these no longer worked. These user controls do all contain RadDocking controls within them.
I currently have 20+ top level controls, with more on the way, that need to be displayed in the RadDocumentPane.Content, and for which extensive re-writing is not viable.

Hi Liam,
As the exception says placing Docking control in another Docking control is not supported, because it causes some issues. For situations like yours we've added a property to the Docking control called AllowUnsafeMode. If you set it to true (on the inner Docking control), you will disable the error. We don't recommend to do this, but we understand that sometimes it is too complex to migrate the architecture.
