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.

Example

This example sets the LoadOnDemandTriggerMode property.

protected void Page_Load(object sender, System.EventArgs e)
{
FpSpread1.ActiveSheetView.RowCount = 100;
FpSpread1.ActiveSheetView.PageSize = 200;
FpSpread1.ActiveSheetView.AllowPage = false;

FpSpread1.AllowLoadOnDemand = true;
FpSpread1.LoadInitRowCount = 50;
FpSpread1.LoadRowIncrement = 15;
FpSpread1.ActiveSheetView.LoadOnDemandMode = FarPoint.Web.Spread.LoadOnDemandMode.Background;
FpSpread1.ActiveSheetView.LoadOnDemandTriggerMode = FarPoint.Web.Spread.LoadOnDemandTriggerMode.OffsetBased;
FpSpread1.ActiveSheetView.LoadOffsetFromBottom = 20;
FpSpread1.ActiveSheetView.LoadOnDemandInterval = 1000; // this setting is meaningless in OffsetBased trigger mode
}

VB.NET

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
