title: Firing a Command within EventTrigger of a style?
body: <p>As you know you can't bind an Event directly to a command without a behaviour:</p>
  
  <pre><code>&lt;DataGrid&gt;
      &lt;i:Interaction.Triggers&gt;
          &lt;i:EventTrigger EventName="PreviewMouseDoubleClick"&gt;
              &lt;i:InvokeCommandAction Command="{Binding TradeEntryCommand"} /&gt;
          &lt;/i:EventTrigger&gt;
      &lt;/i:Interaction.Triggers&gt;
  &lt;/DataGrid&gt;
  </code></pre>
  
  <p>This works perfectly fine, however now I have to refactor this from double clicking the DataGrid itself to double clicking the Cell. (I don't care which cell was clicked)</p>
  
  <p>I was hoping to define this behviour now inside the Cell Style like this:</p>
  
  <pre><code>&lt;Style x:Key="DefaultCellStyleBase" TargetType="{x:Type DataGridCell}"&gt;
      &lt;Setter Property="Template"&gt;
          &lt;Setter.Value&gt;
              &lt;ControlTemplate TargetType="{x:Type DataGridCell}"&gt;
                  &lt;ControlTemplate.Triggers&gt;
                      &lt;EventTrigger RoutedEvent="PreviewMouseDoubleClick"&gt;
                          ?????????
                      &lt;/EventTrigger&gt;
                  &lt;/ControlTemplate.Triggers&gt;
              &lt;/ControlTemplate&gt;
          &lt;/Setter.Value&gt;
      &lt;/Setter&gt;
      &lt;!-- ... --&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>But how would I bring in the behaviour from above to fire the command?  </p>
  
  <p>Highly appreciated,</p>
