Implement Swipe Event on WP8

I am creating a wp8 application to display some html files in a browser, and the structure

    <Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid Name="PageNavigationMenu">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto"/>
            <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>
        <Button Height="70" Content="P"  Grid.Column="0"  VerticalContentAlignment="Center" Click="btnPrevious_Click" x:Name="btnPrevious" ></Button>
        <Button Height="70"  Content="N"  Grid.Column="1" VerticalAlignment="Center"  Click="btnNext_Click" x:Name="btnNext"></Button>
    </Grid>
    <Grid Grid.Row="1" Hold="Grid_Hold">
        <phone:WebBrowser IsScriptEnabled="True" x:Name="mainBrowserControl">

        </phone:WebBrowser>
    </Grid>
</Grid>

Now I use the previous button and the next button to change the content in the browser. I want to do this using Swipe Left / Swipe Right in the browser. For example, if the user scrolls left, the contents of the border should be loaded with the previous page, and the results of Swipe right should be loaded to load the next page.

So what are the events that I have to listen to implement the scroll function

(AFAIK):
XNA TouchPanel ( : TouchInput, " " blog) :

public MainPage()
{
   InitializeComponent();

   TouchPanel.EnabledGestures = GestureType.Flick;
   myWebbrowser.ManipulationCompleted += myWebbrowser_ManipulationCompleted;
}

private void myWebbrowser_ManipulationCompleted(object sender, System.Windows.Input.ManipulationCompletedEventArgs e)
{
   if (TouchPanel.IsGestureAvailable)
   {
      GestureSample gesture = TouchPanel.ReadGesture();
      switch (gesture.GestureType)
      {
        case GestureType.Flick:
            if (e.FinalVelocities.LinearVelocity.X < 0)
                        LoadNextPage();
            if (e.FinalVelocities.LinearVelocity.X > 0)
                        LoadPreviousPage();
            break;
        default:
            break;
      }
  }
}

ManipulationEvent (, Pivot Map), Touch.FrameReported - - :

public MainPage()
{
    InitializeComponent();

    TouchPanel.EnabledGestures = GestureType.Flick;
    Touch.FrameReported += Touch_FrameReported;
}

private void Touch_FrameReported(object sender, TouchFrameEventArgs e)
{
   if (TouchPanel.IsGestureAvailable)
   {
      GestureSample gesture = TouchPanel.ReadGesture();
      switch (gesture.GestureType)
      {
         case GestureType.Flick:
             if (gesture.Delta.X > 0)
                  MessageBox.Show("Right");
             if (gesture.Delta.X < 0)
                  MessageBox.Show("Left");
             break;
         default:
             break;
      }
   }

TouchPoint firstPoint;
private void Touch_FrameReported(object sender, TouchFrameEventArgs e)

   TouchPoint mainTouch = e.GetPrimaryTouchPoint(ContentPanel);

   {
       double deltaX = mainTouch.Position.X - firstPoint.Position.X;
       double deltaY = mainTouch.Position.Y - firstPoint.Position.Y;
       if (Math.Abs(deltaX) > 2 * Math.Abs(deltaY))
       {
           if (deltaX < 0) MessageBox.Show("Right.");
           if (deltaX > 0) MessageBox.Show("Left.");
       }
