title: Set default padding on ComboBox dependent on IsEditable property
body: <p>I have set all my TextBoxes and ComboBoxes to have a default Padding of "1,3".  When a ComboxBox is editable, the padding looks identical to the TextBoxes.  But when <code>IsEditable</code> is defaulted to false, the padding doesn't look the same.</p>
  
  <p>In App.xaml I already have:</p>
  
  <pre><code>&lt;Application.Resources&gt;
      &lt;Style TargetType="TextBox"&gt;
          &lt;Setter Property="Padding" Value="1,3"/&gt;
      &lt;/Style&gt;
      &lt;Style TargetType="ComboBox"&gt;
          &lt;Setter Property="Padding" Value="1,3"/&gt;
      &lt;/Style&gt;
  &lt;/Application.Resources&gt;
  </code></pre>
  
  <p>In App.xaml, how can I set all ComboBoxes with an <code>IsEditable="False"</code> property to have <code>Padding="6,3,5,3"</code>?</p>
