title: Dragging over a dragablz:TabablzControl tab to bring it to front
body: <p>I would like to implement a DragEnter-Event for each TabItem of my dragablz:TabablzControl. Tabs should be automatically selected when dragging a file over it.</p>
  
  <p>I found two topics on stackoverflow that seem to be similar to my question:</p>
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/13625387/dragging-over-a-tab-to-bring-to-front">Dragging over a tab to bring to front</a></li>
  <li><a href="https://stackoverflow.com/questions/4439323/wpf-tab-control-drag-n-drop-bring-tab-in-front-behavior">WPF tab control drag 'n
  drop: bring tab in front behavior</a></li>
  </ul>
  
  <p>Unfortunately these solutions doesn't work for TabablzControl from <a href="https://github.com/ButchersBoy/Dragablz" rel="nofollow noreferrer">Dragablz</a>.</p>
  
  <pre><code>&lt;dragablz:TabablzControl Name="TC_FooBar" FixedHeaderCount="3"&gt;
        &lt;TabItem Header="FIRST"&gt;
              &lt;!-- &lt;ContentOfFirstTabItem/&gt; --&gt;
        &lt;/TabItem&gt;
        &lt;TabItem Header="SECOND"&gt;
              &lt;!-- &lt;ContentOfSecondTabItem/&gt; --&gt;
        &lt;/TabItem&gt;
        &lt;TabItem Header="THIRD"&gt;
              &lt;!-- &lt;ContentOfThirdTabItem/&gt; --&gt;
        &lt;/TabItem&gt;
  &lt;/dragablz:TabablzControl&gt;
  </code></pre>
  
  <p>What I have tried so far:</p>
  
  <ul>
  <li>Implementing <code>DragEnter</code> und <code>PreviewDragEnter</code> events for each TabItem and for the TabablzControl itself.</li>
  <li>Setting <code>AllowDrop="True"</code> for TabablzControl and each TabItem.</li>
  </ul>
  
  <p>Everytime the <code>e.Source</code> is equal to the content of the currently selected tab. I'm not able to identify the correct TabItem. Any ideas?</p>
