title: stretch bottom control in stackpanel
body: <p>Only column headers are displayed for DataGrid. How to force the DataGrid to fill all remaining space of StackPanel? And how to force the StackPanel to fill all empty space of it's parent control? There is a lot of empty space below the DataGrid.</p>
  
  <pre><code>&lt;StackPanel Orientation="Vertical"&gt;
  &lt;Label&gt;some text&lt;/Label&gt;
  &lt;DataGrid/&gt;
  &lt;/StackPanel&gt;
  </code></pre>
  
  <p>I know how to solve this using Grid, but I don't want to use it for such simple layout.</p>
