title: Background property not applying
body: <p>Working on an XAML window:</p>
  
  <p>Here is my ComboBox:</p>
  
  <pre><code>&lt;ComboBox ItemsSource="{Binding myStuff}" SelectedItem="{mySelectedStuff}" Background="Red" Foreground="Green" /&gt;
  </code></pre>
  
  <p>My binding works fine, the foreground property applies but the background property doees not apply.
  Whatever value I set, it stays Grey.</p>
  
  <p>Is there anything I might have forgotten?</p>
  
  <p>On other pages, background works fine. I do not manage to determine what is different on this particular page.</p>
  
  <p>This style applies:</p>
  
  <pre><code>&lt;Style TargetType="ComboBox" &gt;
      &lt;Setter Property="Width" Value="90" /&gt;
      &lt;Setter Property="Height" Value="28" /&gt;
      &lt;Setter Property="Margin" Value="10,0" /&gt;
      &lt;Setter Property="FontSize" Value="13" /&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>It does not work better if I set the background property into the style rather than into the control.</p>
  
  <p>EDIT:
  problem solved.
  My style posted was conflicting with another style. If I remove my custom style, it works fine.</p>
  
  <p>Well useless post in the end.
  Thx anyway for your kind assistance.</p>
