title: How to trigger a storyboard on property changed
body: <p>I would like to have a storyboard started, whenever the value of <code>MyCounter</code>changes.<br>
  With a <code>DataTrigger</code> I only can trigger on a specific value.</p>
  
  <pre><code>&lt;DataTemplate.Triggers&gt;
      &lt;DataTrigger Binding="{Binding Path=MyCounter}" Value="Doesn't matter"&gt;
              &lt;BeginStoryboard Storyboard="{StaticResource myStoryboard}"/&gt;
      &lt;/DataTrigger&gt;
  &lt;/DataTemplate.Triggers&gt;
  </code></pre>
