Click Event for Scrollbar

Hi, Do we have any event for scrollbar click?

I am highlighting a row on clicking a down-arrow inside a div. but when i click the down arrow button after dragging the scroll bar, the highlighted row and scroll moves in zig zag manner. so i want to certain functions on scrollbar event, but that should not affect when the scroll bar moves on clicking the down-arrow.

It will be helpful if there is event for the scrollbar click..
