Directly access content area in NavigationView

[mchadhaiz]

Hi, is there a way to directly access the content area/frame in the NavigationView? Currently the only customization I've been able to find is the FrameMargin parameter.

I am interested in this as well. I would like to be able to use the NavigationView like a traditional TabControl.

@pomianowski - Is this even possible?
