title: Making WPF grid slide up when a mouse enters the window
body: <p>I currently have the XAML:</p>
  
  <pre><code>&lt;Grid Name="WindowGrid"&gt;
      &lt;Grid Height="66" HorizontalAlignment="Stretch" Margin="0" Name="ControlsGrid" VerticalAlignment="Bottom" Background="#B4000000" /&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>What I want is when the mouse enters the window (or even WindowGrid, preferably), the ControlGrid slides up, and vice versa (when the cursor leaves, it slides down). I have little experience in WPF/XAML, having most experience in WinForms. I understand there is a way to do this with storyboards/triggers, but the examples I've seen are too confusing.</p>
