MouseWheel event not firing when attached to TreeListView - Grids for WPF Forum

Posted 3 months ago by Mark Tannehill

Version: 24.1.4

Platform: .NET 6.0

Environment: Windows 11 (64-bit)

As title describes, when hooking up a MouseWheel event to TreeListView, the event never fires so I cannot do actions on MouseWheel as intended. Is there another way to access this event? Other events like MouseDoubleClick appear to be working as intended.

Immediately when I used PreviewMouseWheel, it worked.. So I successfully jinxed myself here with this one.

Hi Mark,

I don't think our control handles the mouse wheel directly, but the ScrollViewer in the TreeListView's template definitely processes and handles that event. I'm glad you found a workaround with the preview version of the event.
