Explanation

The ScrollDispImage event is generated when a scroll bar is used to scroll the image. To generate this event, the image must be displayed in actual size and the ScrollBar property must be True.

Note: This event is not generated when a mouse drag is used to scroll the image (when the MouseDragImage property is true). It is only generated when the scroll bar or scroll box is clicked.
