title: Why image don't autosize in grid panel?
body: <p>I tried to make a wp7 app with expression blend. But is there a problem that make me crazy!</p>
  
  <p>I created a <strong>Panorama Controller</strong>, a <strong>Panorama Item</strong> and a <strong>Grid</strong>. In this grid i create an <strong>Image</strong>.<br>
  <img src="https://i.stack.imgur.com/Kx3pK.png" alt="enter image description here"></p>
  
  <p>Why my image <em>won't enlarge on width</em>?</p>
  
  <p>Here the screenshots:<br>

  The gray image is rounded also at dx, like sx side.</p>
  
  <p>Here the config:<br>

  <p>Is there a solution to enlarge my image on width like max size of grid?  </p>
  
  <p>How can I do this?</p>
  
  <p>This is my snippet of code:</p>
  
  <pre><code>&lt;controls:PanoramaItem Foreground="Black" &gt;
    &lt;Grid Margin="1,26,160,46" Width="418"&gt;
      [...]
      &lt;Grid Margin="0,190,8,0" VerticalAlignment="Top" Height="207" &gt;
        &lt;Image Source="JobRow.png" Margin="8,34,27,50" Stretch="None" /&gt;
      &lt;/Grid&gt;
    &lt;/Grid&gt;
  &lt;/controls:PanoramaItem&gt;
  </code></pre>
  
  <p>Any idea please?</p>
  
  <p><strong>EDIT 1</strong>: if I change Stretch this is the result, my image enlarge only in height!<br>
  It's like that is blocked at certain position... but i don't know why!!!</p>

  <p><strong>EDIT 2</strong>: Changing default orientation will not enlarge my grid!</p>
  
  <pre><code>&lt;controls:PanoramaItem Foreground="Black" Width="438" Orientation="Horizontal"&gt;
  </code></pre>
