Right justify button in grid, possibly without content - stretch grid to always fill the page

Question

I'm losing patience. I am working on a Windows Phone 7 application and I cannot figure out which layout manager to use to achieve the following:

Basically, when I use the Grid as the root of the layout, I cannot get the grid to stretch to the page size of the phone application. When the main content area is full, everything is fine, and the button sits where I want it to sit. However, if the content of the page is very short, the grid will be only as wide as for its content, and then the button (which I desperately hold near the right edge of the screen) moves away from the right edge.
