LoadOnDemandTriggerMode Property
Example 


FarPoint.Web.Spread Assembly > FarPoint.Web.Spread Namespace > SheetView Class : LoadOnDemandTriggerMode Property
Gets or sets the LoadOnDemandTriggerMode property. If trigger mode is Timed, spread loads the next set of rows after a period of time until there are no rows to load. If trigger mode is OffsetBased, spread only loads the next set of rows if the user scrolls to the row at the LoadOffsetFromBottom position.
