title: Change background color of ScrollBar in ScrollViewer wpf
body: <p>I know how to change the background color of a scrollbar:</p>
  
  <pre><code>&lt;ScrollBar Height="27" Margin="36,96,12,0" Name="scrollBar1" Background="Red"&gt;&lt;/ScrollBar&gt;
  </code></pre>
  
  <p>here is the picture with my red background:

  <p>How could I do the same thing with ScrollViewer? I have a grid inside my ScrollViewer and if I change the properties of ScrollViewer it seem to change the properties of the content inside my grid. </p>
  
  <pre><code>&lt;ScrollViewer&gt;
  
  
      &lt;Grid Name="Parent"&gt;
          &lt;Grid.RowDefinitions&gt;
              &lt;RowDefinition Height="Auto" /&gt;
              &lt;RowDefinition Height="Auto" /&gt;
               ....
               ....
               ... etc
  </code></pre>
  
  <p>that produces:</p>

  <p>with the content of my grid named Parent on the left. How could I place a red background on this ScrollViewer?</p>
