Windows phone 8 popup width and height

Question

I place the grid in a popup control. I expected the grid to be resized automatically according to three different layout sizes for Windows 8 applications ( 480 × 800, 768 × 1280, 720 × 1280 ).

But it seems to me that I would need to set the width and height of the grid explicitly , because it redefines itself according to the size of the child control, whereas I need a pop-up window that will be shown as full at the top of the screen for all three resolutions.

Any help?
