That is because touch pad is no longer firing PointerWheelChanged events. Here is a quote from the documentation:

Starting with Windows 8.1, ScrollViewer uses an underlying manipulation logic that interprets track pad gestures as actions that the ScrollViewer responds to, and thus the gesture is considered handled by the control and the PointerWheelChanged event is not fired anymore.

so, is there a way if I want to catch that event? I need to override ScrollViewer? – Hoka Biu Feb 27 '23 at 05:53
The ``ListView`` should scroll when you do scroll touch gestures on touchpad. Do you just need an event fired? or you need the precise delta values of the scroll event? – Andrew KeepCoding Feb 28 '23 at 06:29
I just need an event fired to add other behavior when scroll up or down in ListView – Hoka Biu Mar 22 '23 at 06:17
