title: Getting the coordinates of a specific ListViewItem relative to it's owning ListView
body: <p>I'm trying to determine the physical coordinates (specifically I'm interested in the TOP and BOTTOM) of the container which represents the ListViewItem.</p>
  
  <p>I have a reference to the ListViewItem via:</p>
  
  <pre><code> ListViewItem item = ((ListView)AdornedElement).ItemContainerGenerator.ContainerFromIndex(idx) as ListViewItem;
   ContentPresenter myContentPresenter = FindVisualChild&lt;ContentPresenter&gt;(item);   
  </code></pre>
  
  <p>I now need to take the item and figure out what it's top and bottom values are relative to the entire listview.  This is for showing a dragline indicator during a drag drop.</p>
  
  <p>Can anyone offer any insight?</p>
  
  <p>Thanks</p>
