body: <p>Is there a way I can get the index of a tapped item in the AdaptiveGridView toolkit.
  Heres my code:
  Page Resources:</p>
  
  <pre><code>&lt;Page.Resources&gt;
      &lt;DataTemplate x:Key="Photos"&gt;
          &lt;Grid&gt;
              &lt;Image Source="{Binding ImageURL}"
                         Stretch="UniformToFill"
                         HorizontalAlignment="Center"
                         VerticalAlignment="Center"&gt;
              &lt;/Image&gt;
              &lt;TextBlock Text="{Binding ImageText}"
                         FontSize="20"&gt;
              &lt;/TextBlock&gt;
          &lt;/Grid&gt;
      &lt;/DataTemplate&gt;
  &lt;/Page.Resources&gt;
  </code></pre>
  
  <p>XAML:</p>
  
  <pre><code>  &lt;UWPToolkit:AdaptiveGridView x:Name="AdaptiveGV" ItemHeight="200" ItemClick="AdaptiveGV_ItemClick" DesiredWidth="200" ItemTemplate="{StaticResource Photos}"/&gt;
  </code></pre>
  
  <p>Code behind:</p>
  
  <pre><code>    List&lt;Images&gt;   ImageCollection = new List&lt;Images&gt;();
  
  ImageCollection.Add(new Images()
                      {
                          ImageURL = Response[i].ProjectImageURL,
                          ImageText = Response[i].ProjectName
  
                      });
                  }
                  AdaptiveGV.ItemsSource = ImageCollection;
  </code></pre>
