title: Binding fails without error
body: <p>I have a CustomListView that has controls like <code>TextBoxes</code>, <code>HyperLinks</code> and <code>Buttons</code>.<br>
  I can't share the exact Code, but please bear with me.</p>
  
  <p>I have a list, say of type person with attributes like <code>personHeight</code>, <code>personWidth</code>, etc.<br>
  The binding to the list is done at the list level. </p>
  
  <p>The issue is, that all values are fetched from the database, but only one is populated, the remaining are blank.<br>
  Also I didn't get any binding error in the Output Window. <strong>What could be the issue?</strong></p>
  
  <p>The general syntax of the XAML (where <code>personHeight</code> is one of the properties of the list object):</p>
  
  <pre><code>&lt;CustomGridViewColumn SortOnProperty="personHeight"&gt;
      &lt;CustomGridViewColumn.SortableHeader&gt;
          &lt;TextBlock Text="Person Height" /&gt;
      &lt;/CustomGridViewColumn.SortableHeader&gt;
      &lt;CustomGridViewColumn.CellTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;TextBox x:Name="personHeightText" Text="{Binding personHeight}" /&gt;
          &lt;/DataTemplate&gt;
      &lt;/CustomGridViewColumn.CellTemplate&gt;
  &lt;CustomGridViewColumn&gt;
  </code></pre>
  
  <p>The binding is done as follows:</p>
  
  <pre><code>&lt;CustomListView ItemsSource="{Binding Path=Persons}"
                  ItemContainerStyle="{StaticResource MyExpandableListViewItemStyle}"
                  ExpandedDataTemplate="{StaticResource ExpandedDataTemplate}"
                  ScrollViewer.CanContentScroll="False"
                  x:Name="GridList"&gt;
  </code></pre>
