I'm trying to bind the Source of a CollectionContainer (or CollectionViewSource for that matter) to a RelativeSource Binding - I always get the following error
System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element.
I understand this is due to CollectionContainer not being Freezable or not deriving from FrameworkElement.
Has anyone got a solution/workaround for this problem. I have seen talk of trying to implement their own Freezable CollectionContainer - any luck with this approach?
Thanks, Pete
