title: Binding WPF Image control events with MVVM Light EventToCommand
body: <p>I want to wire command to Image's MouseDown event in WPF MVVMLight applcation. I have following code :</p>
  
  <pre><code>&lt;Border Grid.Row="2" Grid.Column="1" BorderThickness="1" BorderBrush="Black"&gt;
                  &lt;Image Margin="3" Name="Content" Source="{Binding Content}" HorizontalAlignment="Left"&gt;
                      &lt;i:Interaction.Triggers&gt;
                          &lt;i:EventTrigger EventName="MouseDown"&gt;
                              &lt;cmd:EventToCommand 
                                  Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.SelectMediaCommand}" 
                                  CommandParameter="{Binding}"/&gt;
                          &lt;/i:EventTrigger&gt;
                      &lt;/i:Interaction.Triggers&gt;    
                  &lt;/Image&gt;
              &lt;/Border&gt;
  </code></pre>
  
  <p>When i paste &lt; Triggers > piece into other control (say textblock in same view), MouseDown does occur (bindings are correct). Tried even put it inside Border, still no effect. I guess i'm missing something. Any ideas what? Thanks in advance.</p>
