If I add a Column Header or Footer to a GridViewColumn an InvaidOperationException is thrown with a message of "Specified element is already the logical child of another element. Disconnect it first." when I attempt to change the Theme. If I comment out the footer, there is no exception and the theme changes as expected.
Below are the exception details and following that, the the xaml for the RadGridView.
System.InvalidOperationException was unhandled
Message=Specified element is already the logical child of another element. Disconnect it first.
