title: Windows Store Apps: Grid View Group Binding background color?
body: <p>I have a grid view with a CollectionViewSource as it's items source.</p>
  
  <p>I want to to bind the background property of each group container panel so that each group has its own background color.</p>
  
  <p>how can this be achieved?</p>
