        ContentFrame.GoBack()
    End If
End Sub

Private Sub ForwardNavButton_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
    If (ContentFrame.CanGoForward) Then
        ContentFrame.GoForward()
    End If
End Sub

private void BackNavButton_Click(object sender, RoutedEventArgs e)
{
    if (ContentFrame.CanGoBack)
    {
        ContentFrame.GoBack();
    }
