title: WPF Toolbar Items HorizontalAligment="Right"
body: <p>Is it possible to make the elements within a WPF toolbar have a HorizontalAlignment of Right?</p>
  
  <pre><code>&lt;ToolBar Height="38" VerticalAlignment="Top" Grid.Row="1"&gt;
      &lt;Button HorizontalAlignment="Left" Width="50" VerticalAlignment="Stretch"/&gt;
      &lt;Button HorizontalAlignment="Left" Width="50" VerticalAlignment="Stretch"/&gt;
      &lt;ComboBox Width="120" HorizontalAlignment="Right"/&gt;
  &lt;/ToolBar&gt;
  </code></pre>
  
  <p>I've tried adding the elements inside into a Grid and assigning the <code>ColumnDefinition</code>s to Left/Right as well. I have also tried a <code>StackPanel</code>. No matter what I try I can't seem to get the ComboBox to be "anchored" on the right side of the Toolbar.</p>
  
  <p><strong>UPDATE:</strong></p>
  
  <pre><code>&lt;DockPanel LastChildFill="True"&gt;
  </code></pre>
  
  <p>Doesn't work, It will not fill the ToolBar element like it would a normal element.</p>
