how can I synchronize two scroll bars?

<RichTextBox ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Visible" Name="TextInput" AcceptsReturn="True" TextChanged="TextChangedEventHandler" Margin="0,23,0,9" ScrollViewer.ScrollChanged="OnScrollChangedHandler" HorizontalScrollBarVisibility="Visible" Grid.RowSpan="2" Grid.ColumnSpan="9" HorizontalAlignment="Right" Width="432.493">

            <RichTextBox.Resources>

                <Style TargetType="{x:Type Paragraph}">

                    <Setter Property="Margin" Value="0"/>

                </Style>

            </RichTextBox.Resources>

        </RichTextBox>

 

    <ScrollViewer Name="ScrollRow" VerticalScrollBarVisibility="Visible" ScrollViewer.ScrollChanged="OnRowsScrollChangedHandler" ScrollViewer.HorizontalScrollBarVisibility="Visible" Grid.RowSpan="2" Margin="0,23,0,7.02" HorizontalAlignment="Left" Width="40">

                    <StackPanel Name="pScrollRow">

                      <ListView Margin="0,23,0,9" Name="Rows">

                        1.

                      </ListView>

          </StackPanel>

           </ScrollViewer>

       

// ...

 

 private void OnScrollChangedHandler(object sender, ScrollChangedEventArgs e)

        {

            ((IScrollInfo)pScrollRow).SetHorizontalOffset(e.HorizontalOffset);

        }
