title: How to tell Size of a Grid Cell?
body: <p>I have a custom control that I've placed inside a cell of a grid.  I have some internal calculations I need to run based on the height and width of the custom control.  However, I want it to resize based on the size of the cell.  </p>
  
  <p>So, my main question is... how to I programatically determine the height and width of a given cell?  </p>
