I’m attempting to build a C Metro app that uses SwapChainBackgroundPanel. I want to use Blend for XAML overlaysThe only example I have found so far that actually uses Blend is Simple3DGameXaml (the shoot at the rectangle targets app.)Looking at MainPage.xaml for the sample, it has a Page element, a bottom and top AppBar (not really relevant to the question), and a SwapChainBackgoundPanel.

The first button is visible only in some situations so I hide it binding its Visibility to a viewmodel boolean property, using a converter to convert from bool to Visibility.The button is correctly collapsed but it still has the same size so I have an empty space in the grid.How can I hide the button and avoid the empty space?

Is this going to change before the finalrelease of Windows 8?No matter where you go, there you are.
