title: Change Background on DragEnter
body: <p>I want to change the background of a framework element when the DragEnter event is fired and revert its background when the DragLeave event is fired. Additionally, I want this applied in a style.</p>
  
  <p>Heres what I have currently:</p>
  
  <pre><code>&lt;EventTrigger RoutedEvent="Button.DragEnter"&gt;
              &lt;BeginStoryboard x:Name="DragHoverStoryboard"&gt;
                  &lt;Storyboard&gt;
                      &lt;DoubleAnimation Storyboard.Target="??????????"
                                       Storyboard.TargetProperty="Background"
                                       Duration="0:0:0"
                                       To="{DynamicResource HoverBrush}" /&gt;
                  &lt;/Storyboard&gt;
              &lt;/BeginStoryboard&gt;
          &lt;/EventTrigger&gt;
          &lt;EventTrigger RoutedEvent="Button.DragLeave"&gt;
              &lt;StopStoryboard BeginStoryboardName="DragHoverStoryboard" /&gt;
          &lt;/EventTrigger&gt;
          &lt;EventTrigger RoutedEvent="Button.Drop"&gt;
              &lt;StopStoryboard BeginStoryboardName="DragHoverStoryboard" /&gt;
          &lt;/EventTrigger&gt;
  </code></pre>
  
  <p>The problem here is that I can't apply target by a name because this style can be applied to any FrameworkElement. How do I apply the target to the element that the Style is attached to?</p>
