title: WPF Trigger Properties
body: <p>I am fairly new to WPF and I am currently working with <a href="http://msdn.microsoft.com/en-us/library/system.windows.trigger.aspx" rel="noreferrer"><code>triggers</code></a>.  I have a question regarding a <em>simple trigger</em>.  By <em>simple trigger</em>, I mean one that watches for a change in a <a href="http://msdn.microsoft.com/en-us/library/system.windows.dependencyproperty.aspx" rel="noreferrer"><code>dependency property</code></a> and uses a <a href="http://msdn.microsoft.com/en-us/library/system.windows.setter.aspx" rel="noreferrer"><code>setter</code></a> to change the style. </p>
  
  <p>Example:</p>
  
  <pre><code>&lt;Style.Triggers&gt;
      &lt;Trigger Property="Control.IsFocused" Value ="True"&gt;
          &lt;Setter Property=" Control.Foreground" Value =" DarkRed" /&gt;
      &lt;/Trigger&gt;
  &lt;/Style.Triggers&gt;
  </code></pre>
  
  <p>All examples I have seen have used the following <a href="http://msdn.microsoft.com/en-us/library/system.windows.trigger.property.aspx" rel="noreferrer"><code>trigger properties</code></a>:</p>
  
  <ul>
  <li><code>&lt;Trigger Property="Control.IsFocused" Value ="True"&gt;</code></li>
  <li><code>&lt;Trigger Property="Control.IsMouseOver" Value ="True"&gt;</code></li>
  <li><code>&lt;Trigger Property="Button.IsPressed" Value ="True"&gt;</code></li>
  </ul>
  
  <p><strong>Question</strong>:
  Are these the <em>only</em> trigger properties available? If not, what others exist?</p>
  
  <p>I have searched online but to no avail. Maybe someone could shed some light on this.</p>
