title: How to use both Command and EventTrigger in DataTemplate Button?
body: <p>I have a Button in a DataTemplate that is bound to a Command in my ViewModel. The button also has an EventTrigger that kicks off a Storyboard that hides the edit controls (of which the button is a part.)</p>
  
  <p>The Storyboard works fine if I pick up the PreviewMouseDown event, but the Command never gets called. If I pick up the MouseDown event in my EventTrigger, the Command works, but the Storyboard doesn't execute.</p>
  
  <p><strong>How can I get both the Command and the Storyboard to execute when the button is clicked?</strong></p>
  
  <pre><code>&lt;Button Content="Save" Command="{Binding SaveCommand}" &gt;
      &lt;Button.Triggers&gt;
          &lt;EventTrigger RoutedEvent="Button.PreviewMouseDown"&gt;
              &lt;EventTrigger.Actions&gt;
                  &lt;BeginStoryboard Storyboard="{DynamicResource sbCloseTitleEdit}"/&gt;
              &lt;/EventTrigger.Actions&gt;
          &lt;/EventTrigger&gt;
      &lt;/Button.Triggers&gt;
  &lt;/Button&gt;
  </code></pre>
