I have a combobox control’s previewmousewheel event been handled. When my mouse is on the control and i move the center wheel of my mouse then this event gets raised. But when my mouse is away from the control and i move the center wheel of my mouse then this event does not get raised.
Can anybody please explain me why is this happening?
If I want to raise an event when my mouse is away from the control then which event should I handle?
This is expected behaviour.
If the mouse cursor is not positioned over the control then no mouse events are routed through it. You wouldn’t expect a mouse click event to be routed through it if the cursor was over a different control would you?
If you want this behaviour then I would suggest that you handle the mousewheel event in the page/view and route it from there, be cautious though as user expectation is for mouse and keyboard events to be handled by the in focus item.
