title: Setting background to GroupTableViewBackgroundColor
body: <p>I have a UIViewController in my Monotouch iPhone application and I want to set the background to what you have in a UITableViewStyle.Grouped.  However when I use the code below it returns a black screen.</p>
  
  <pre><code>this.View.BackgroundColor = UIColor.GroupTableViewBackgroundColor;  // Black screen
  this.View.BackgroundColor = UIColor.Red; // Works
  </code></pre>
  
  <p>I call these in the ViewWillAppear method.  If I comment out the GroupTable then the background gets set to Red.  When I comment out the second line all I get is a black screen.  </p>
  
  <p>Does anyone know why this is?  Can you not call UIColor.GroupTableViewBackgroundColor if your not in a UITableViewController?</p>
  
  <p>Thanks</p>
