RadSplitContainer throws exceptions in Form Designer

[Pete Davis]

I'm using RadControls_for_WPF35_2010_3_1314_Dev in VS.NET 2010.

When I drop a SplitContainer in brand new empty Window, I get one of two errors (it seems to randomly do one or the other):

Exception of type 'MS.Internal.Validate+ValidationFailure' was thrown

or

Value cannot be null
Parameter name: viewItem is null

The latter error shows twice in the same message box. Once like that and a second time in quotes.

Any ideas?

Hi Pete,

 
Unfortunately, we don't support using RadSplitContainer outside of the RadDocking control. For more information, please refer to the following link - http://www.telerik.com/help/wpf/raddocking-features-split-container.html

Best wishes,
