title: Windows universal app - Show popup grid from parent control
body: <p>I'm struggling to get something similiar to <a href="https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpt1/v/t34.0-12/11198788_10204946067036728_217309054_n.jpg?oh=78d92f11f4bbf24053c8051a0b294908&amp;oe=554A092F&amp;__gda__=1430988868_fe87a8baa6aa66ca544f9e415cb0fb03" rel="nofollow">what I painted</a> in Photoshop (took over 9000 hours).</p>
  
  <p>Basically our Windows app for tablets needs a control that shows an onscreen grid when clicked. The data genesis and grid preparation occurs in codebehind of the control and I don't know how to draw the grid outside of my control. Even simple popup control would be fine if I could get it outside the parent boundaries.</p>
