title: TextBox with background image and color
body: <p>I have a TextBox control and I would like to be able to set a background image and a background color.</p>
  
  <p>Currently I can set one, or the other but not both. When I try to set both simultaneously I receive a "The property 'Background' is set more than once" error.</p>
  
  <p>Here is the code I used:</p>
  
  <pre><code>&lt;TextBox Name="tbImageTextBox"&gt;
        &lt;TextBox.Background&gt;
             &lt;ImageBrush ImageSource="/Resources/Images/image.png" 
                    AlignmentX="Right" Stretch="None"/&gt;
             &lt;SolidColorBrush&gt;#FF8D8A8A&lt;/SolidColorBrush&gt;
        &lt;/TextBox.Background&gt;
  &lt;/TextBox&gt;
  </code></pre>
  
  <p>I have also attempted to set the background color in the style for the TextBox and the image in the <code>&lt;TextBox.Background&gt;</code>, but the color is ignored.</p>
