title: How to animate TextBlock when its value changes in WinRT XAML?
body: <p>I have the following <code>Storyboard</code></p>
  
  <pre><code>&lt;Storyboard x:Name="DeleteStoryboard"&gt;
      &lt;DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="StatusTextBlock"&gt;
          &lt;EasingDoubleKeyFrame KeyTime="0" Value="1"/&gt;
          &lt;EasingDoubleKeyFrame KeyTime="0:0:4" Value="1"/&gt;
          &lt;EasingDoubleKeyFrame KeyTime="0:0:5" Value="0"/&gt;
      &lt;/DoubleAnimationUsingKeyFrames&gt;
  &lt;/Storyboard&gt;
  </code></pre>
  
  <p>and the following <code>TextBlock</code></p>
  
  <pre><code>&lt;TextBlock x:Name="StatusTextBlock" Text="{Binding Status}"&gt;
  </code></pre>
  
  <p>Both are in <code>SettingsFlyout</code> not a <code>Page</code>.</p>
  
  <p>I want the <code>Storyboard</code> to start when the <code>TextBlock</code> value changes.</p>
  
  <p>I'm using MVVM, so please no code-behind stuff unless absolutely necessary.</p>
  
  <p>I tries searching for hints and tried different combination of <code>Behaviors</code>, <code>Triggers</code> and <code>VisualState</code> but reached nowhere.</p>
