title: EventTrigger with Setter in WPF?
body: <p>I have a normal Button and TextBox in a WPF-Window and I want a Template for the Button with a EventTrigger that listens to Button.Click and then sets a boolean-property of the TextBox. No code-behind.</p>
  
  <p>Something like this:</p>
  
  <pre><code>&lt;ControlTemplate.Triggers&gt;
    &lt;EventTrigger SourceName="MyButton" RoutedEvent="Button.Click"&gt;
      &lt;Setter TargetName="MyTextBox" Property="Focusable" Value="False" /&gt;
    &lt;/EventTrigger&gt;
  </code></pre>
