Mousewheel event...

I seem to be missing something... I want to use a mousewheel event in my
VB.NET app... and there's a lot of example code on the net showing how to use
the mousewheel event... and the .NET docs discuss the mousewheel event...

but there doesn't seem to BE a mousewheel event. in VS 2003 or 2005, in C#
or in VB.NET... and on the couple systems I've checked. I can't find a
single control that gives me a "MouseWheel" event option in it's properties.

Anyone see this before... what the heck am I doing wrong?

To save memory, most Control events are not 'real' events. When you
subscribe and unsubscribe, you are adding a delegate to a runtime list
of event handlers; when the event fires, the control has to find the
delegate in a list. Accordingly, the property grid entries for these
events take a bit of property grid 'magic' and (for some reason) this
magic was not applied to the MouseWheel event.

However, if you edit the InitializeComponent method, you will find
that Intellisense DOES know about the MouseWheel event, and Visual
Studio will do the usual auto-complete stuff for you, up to and
including creating a event handler stub.

Hi Dave,

This is a known issue that the MouseWheel event doesn't appear in the
property grid. However, we can still handle this event via code. Please
check the following link for more information.
