WPF DataGrid Auto Scrolling

Auto Scrolling for as long as the the mouse button is down on a button control.

The XAML

Page Down

The Code

    private bool pagedown = false;
    private DispatcherTimer pageDownTimer = new DispatcherTimer();

    private void XBTNPageDown_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        pagedown = true;
        pageDownTimer.Interval = new TimeSpan(0, 0, 0, 0, 30);
        pageDownTimer.Start();
        pageDownTimer.Tick += (o, ea) =>
        {
            if (pagedown)
            {
                var sv = XDG.FindVisualChild();
                sv.PageDown();
                pageDownTimer.Start();
            }
            else
            {
                pageDownTimer.Stop();
            }
        };
    }

    private void XBTNPageDown_MouseUp(object sender, MouseButtonEventArgs e)
    {
        pagedown = false;
    }

This is the extension method

Place it in a static class of your choice and add reference to code above.

   public static T FindVisualChild(this DependencyObject depObj) where T : DependencyObject
    {
        if (depObj != null)
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
                if (child != null && child is T)
                {
                    return (T)child;
                }

                T childItem = FindVisualChild(child);
                if (childItem != null) return childItem;
            }
        }
        return null;
    }

NOTE: The property sv could be moved to avoid repeated work.

Anyone have an RX way to do this?
