[RESOLVED] How to raise event trapping mouse wheel scroll?

[Traps]

I cant seem to figure out how to raise an event that will pass the delta value for mouse scroll from a user control to main form.

I see that MouseEventArgs has delta as one of its properties. With that in mind I have defined

publiceventMouseEventHandler OnMouseActivity;

in my user control, and raise the event

 
privatevoid KeystrokesDetails_MouseMove(object sender, MouseEventArgs e)
{
OnMouseActivity(this, e);
}

as well.......


In my main program, immediately after I create an instance of the user control(the user control is added to a split container panel2 controls collection), I set up the event like this ..........

newDetails.OnMouseActivity += newMouseEventHandler(MouseMoved);

and have a method programmed to handle the event....

 
privatevoid MouseMoved(object sender, MouseEventArgs e)
{
if (e.Delta == 120)
{
splitContainer2.Panel2.VerticalScroll.Value += splitContainer2.Panel2.VerticalScroll.SmallChange;
}
else if (e.Delta == -120)
{
splitContainer2.Panel2.VerticalScroll.Value += splitContainer2.Panel2.VerticalScroll.SmallChange;
}
}

This doesnt work. Delta is always 0. How can I isolate the Delta value?
