title: windows phone 8 popup width and height
body: <p>I am placing a grid in a popup control. I expected the grid to be re-sized automatically according to the 3 different layout sizes for windows phone 8 apps (<strong>480 × 800, 768 × 1280, 720 × 1280</strong>). </p>
  
  <p>But it seems like i would have to set the <strong>width and height</strong> of the grid <strong>explicitly</strong> because it's re-sizing itself according to child control size whereas i wanted the popup box to be shown as full with on the top of the screen for all three resolutions.</p>
  
  <p>Any Help?   </p>
