onpagedown event (Grid)

The onpagedown event activates when the user pages down using the paging scrollbar on a Grid widget.  The "scrollbar" property must be set to "paging" (or to "true" in Genie) for this event to work.  To prevent the grid's default paging action, the JavaScript expression for this event must evaluate to false.

The paging scrollbar is typically used in Genie.  In a Rich Display File environment, the Paging Bar is usually used instead.
