Stackable DockableContent?

Nov 8, 2010 at 5:22 PM

I'm new to AvalonDock so bear with me here.

I've got three DockableContent blocks (with treeviews inside of each) within a ResizingPanel. They render fine as three tabs Horizontally, Is there any way to make each of the DockableContent blocks to stack on top of one another and be visually rendered?  (Kind of like being in a StackPanel). I had though that setting the Orientation of their containing ResizingPanel to "Vertical" would have done it (just a guess) but it doesn't.

Thanks...Paul
