title: Create a full screen GridView in XAML
body: <p>I want to create a full screen GridView control for a Metro Style application in Windows 8 that grows and adapts to the user changing their screen resolution.</p>
  
  <p>I'm trying to imitate the calendar application on Windows 8, wen you swap the metro screen between monitors, the size of each square (date) changes so that the screen is always filled.</p>
  
  <p>Typically you would have a fluid <code>ItemTemplate</code> I need to ensure that the whole screen is full, so sometimes the GridView items will be small (when running on a tablet) and sometimes they will be large (when running on my Desktop).</p>
  
  <p>Can I achieve this using XAML or do I have to get funky with changing the <code>ItemTemplate</code> for the GridView when the screen size changes?</p>
