Example

This example sets the LoadOnDemandMode enumeration.

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.Sheets[0].LoadOnDemandMode = FarPoint.Web.Spread.LoadOnDemandMode.Background;
FpSpread1.Sheets[0].LoadOnDemandTriggerMode = FarPoint.Web.Spread.LoadOnDemandTriggerMode.Timed;
FpSpread1.Sheets[0].LoadOnDemandInterval = 1000; // after every second, perform load on demand 
FpSpread1.Sheets[0].LoadOffsetFromBottom = 20; // this setting is meaningless in Timed trigger mode 
}
