Touchscreen vertical scrolling

Post by Phil14 » Mon Jul 28, 2014 10:58 am


I developed an Windows Form Application with VS 2010 and GdPicture
I use GdViewer to view a Pdf File

I have a problem when I use srcolling within a page :

When I Scroll through the client area vertically or horizontally with the mouse (MouseModePan), all works fine.
When I try to do it with my finger on a touchscreen, the horizontal scroll works, but the vertical scroll doesn’t work.
For horizontal scroll, I get the following events :
- MouseDown event
- several ScrollViewer events
- MouseUp event
For vertical event, I get ScrollViewer events but no MouseDown event (and no Mouseup event)

There is the same problem with your WPF sample.

Can you help me ?

Thank you
