How Do I Capture Mouse Wheel Movements?

[Tony Lin]

I have a Microsoft wheel mouse. When focus is on a scrollable panel, I
would like to capture mouse wheel movement events to make the panel scroll
as the wheel is turned.



I don't see a mouse wheel event in the Windows.Forms.Control or panel
control.



Is there a way I can capture this in .NET?



Thanks.

Mouse wheel detents are in the Delta property of the MouseEventArgs. You
should be able to detect this through the mousemove event.
