I have a windows application (c#) which does not display any scroll bar (I
really don't want it to!). However, I want to capture when the mouse
scroll-wheel is used to "page-through" some of my data, without recourse to
a scroll-bar. Can I capture when the mouse scroll-wheel is used? If so how ?

Override the control's 'OnMouseWheel' method.

it should also be told that only the focused control will get mouse wheel
event

Well I ended up using the MouseWheel event rather than the OnMouseWheel
method: I found this by browsing the documentation, but strangely enough the
event did not appear in the intellisense list, which is why I missed it.

Thanks.

Make sure you have "Hide Advanced members" in the setting turned off.

Thanks, but where is this setting ? There are so many under Options I can't
find it !
