title: WPF ComboBox: background color when disabled
body: <p>I currently use this style for my ComboBox in WPF:</p>
  
  <pre><code>    &lt;Style TargetType="ComboBox"&gt;
          &lt;Setter Property="Foreground" Value="White"/&gt;
          &lt;Setter Property="Background" Value="#303030"/&gt;
          &lt;Setter Property="BorderBrush" Value="#000000"/&gt;
      &lt;/Style&gt;
  </code></pre>
  
  <p>How can I change it to specify the background color when the ComboBox is disabled?</p>
