title: Draw Diagonal Line in WPF Grid
body: <p>I think I am trying to do something relatively simple in WPF, but can't for the life of me figure out how; and think I am probably on the verge of overcomplicating it.</p>
  
  <p>If I had a grid which was 3 rows and 3 columns, and I wanted to join the corners of two cells to create a diagonal border, what would be the best way of doing so?</p>
  
  <p>The lines should ideally re-size if the control is resized (so bound to the corners of the cell?).</p>
  
  <p>Essentially I would like to create the red lines in the diagram hosted here:  <a href="http://imm.io/7A4L" rel="nofollow noreferrer">Example Pic http://imm.io/7A4L</a></p>
