title: devexpress wpf gridcontrol disable context menu
body: <p>I have a <strong>DevExpress grid control</strong> and I want to disable the default context menu that appears when I right click the Grid column headers. To disable this functionality I handled the <code>PreviewMouseRightButtonDown</code> and <code>PreviewMouseRightButtonUp</code></p>
  
  <pre><code>private void UserControl_PreviewMouseRightButtonDown_Up(object sender, System.Windows.Input.MouseButtonEventArgs e)
          {
              e.Handled = true;
          }
  </code></pre>
  
  <p>This is not an acceptable solution. There should be should be something on grid control.  </p>
