title: Autostretch datagrid within a window?
body: <p>I've created a datagrid and placed it in a spot in a WPF form.</p>
  
  <p>Now what I'm trying to do is have the datagrid change its size keeping the same proportions as its original placement with the WPF window changing size (hopefully that makes sense).</p>
  
  <p>I've tried setting autostretch to true but that hasn't helped.</p>
