How do I change a VirtualizingStackPanel's orientation in code behind?

I'm trying to add portrait support to a page containing a GridView that uses a VirtualizingStackPanel as its ItemsPanelTemplate. The idea is that when the orientation changes, I'd be able to change the Orientation property of the VirtualizingStackPanel to scroll vertically in portrait and horizontally in landscape. However, since the VirtualizingStackPanel is used as a template, I can't directly access it by name in the code behind.

Is there any way to accomplish what I want?

I could just make a duplicate of the GridView (or use a ListView) and Visual States to show/hide them appropriately, but I'd prefer not to duplicate so much code.

There is some kind of bug when changing the orientation. 

var zoomedInStackpanel = itemGridView.ItemsPanelRoot as VirtualizingStackPanel;
zoomedInStackpanel.Orientation = Orientation.Vertical;

I gave up and used two GridViews. One for each orientation

Use VisualTreeHelper to dig into the GridView's visual tree and find the panel.
