The LoadPostData member is used primarily by control developers when deriving a custom class from the ImageButton control.

The ImageButton checks to see if the x and y values were posted, which indicates that the image was clicked by the user. The ImageButton then registers with the page that it wants to raise an event during the event-processing phase.
