title: Dynamic LiveTile - adding background image?
body: <p>Working wth live tiles in my Windows Phone 7 app and it's working quite okay.</p>
  
  <p>I'm now trying to create a dynamic live tile and I can't get the background image to show up. When using the code below I only get a black tile. The text I add is shown but not the background image. Image "Build action" is set to "Content".</p>
  
  <p>Any ideas?</p>
  
  <pre><code>StackPanel sp = new StackPanel();
  sp.Height = 173;
  sp.Width = 173;
  
  string fileName = "tile.jpg";
  BitmapImage image = new BitmapImage(new Uri(fileName, UriKind.Relative));
  ImageBrush brush = new ImageBrush();
  brush.ImageSource = image;
  sp.Background = brush;
  
  sp.Measure(new Size(173, 173));
  sp.Arrange(new Rect(0, 0, 173, 173));
  sp.UpdateLayout();
  WriteableBitmap wbm = new WriteableBitmap(173, 173);
  wbm.Render(sp, null);
  wbm.Invalidate();
  </code></pre>
