RadButton not displaying in Nested Grid View

[Matthew]

I'm creating a nested grid view that is three levels deep. I have a parent and a child grid with the child grid containing a tab control with two additional grids. The grids and everything load properly, however the buttons in the tab items are never being displayed (Add Hedging Default and Add Tank Bottom).
Do you see anything wrong with the XAML that would prevent them from being displayed? I've removed the stack panel, tried other buttons, set the size explicitly, etc without any change. 

At this point I'm at a loss of where to go from here.

Thank you

Hello,

Thank you for sharing the code you use.

It seems that the RadButton is visualized under the GridView. Would you please remove the 

HorizontalAlignment="Center" setting of the StackPanel?

Let me know how this works for you.
