If you wrap your rich text boxes in a scroll viewer control

<ScrollViewer ScrollChanged="ScrollViewer_ScrollChanged_1" Name="scvOriginal">
          <RichTextBox Name="rtbOrginal"   ScrollViewer.CanContentScroll="True" />
</ScrollViewer>

<ScrollViewer Name="scvChanged">
          <RichTextBox Name="rtbChanged" ScrollViewer.CanContentScroll="True" />
</ScrollViewer>

Then tap into the scroll changed event of the scroll viewer

 private void scvOriginal_ScrollChanged(object sender, ScrollChangedEventArgs e)
 {
     scvChanged.ScrollToVerticalOffset(e.VerticalOffset);
 } 

This will allow to to set the horizontal and vertical scroll of the 2 rich text boxes.
