FarPoint.Web.Spread Assembly > FarPoint.Web.Spread Namespace > SheetView Class : LoadOnDemandTriggerMode Property


Glossary Item Box

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.

Syntax

Visual Basic (Declaration) 
Public Property LoadOnDemandTriggerMode As LoadOnDemandTriggerMode
Visual Basic (Usage)Copy Code
Dim instance As SheetView
Dim value As LoadOnDemandTriggerMode

Example

This example sets the LoadOnDemandTriggerMode property.
C#Copy Code
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.NETCopy Code
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
FpSpread1.ActiveSheetView.RowCount = 100

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
