title: How to change a Path in DataContext in Element?
body: <p>I have a</p>
  <pre><code>&lt;Grid DataContext=&quot;{Binding Path=ListOFFighters[0],
                              Mode=TwoWay,
                              UpdateSourceTrigger=PropertyChanged}&quot;&gt;
  &lt;/Grid&gt;
  </code></pre>
  <p>How can I change the index <code>0</code> in my <code>Path</code>? Perhaps I can do it with converter, but I have no idea how bind it to my <code>DataContext</code> <code>Path</code>.</p>
