Event Data

The event handler receives an argument of type SheetViewStateEventArgs containing data related to this event. The following SheetViewStateEventArgs properties provide information specific to this event.

Property	Description
Handled	Gets or sets whether the event has been handled.
Index	Gets the index of the collection that contains the sheet.
IsSave	Gets whether the state of the sheet is saved.
SheetView	Gets the sheet whose state is to be loaded or to be saved.

Remarks

When the SaveViewStateToSession property is true, spread saves its view state to the Session object. If you do not want to save the spread view state to the Session object, you should set this property to false. The default value is true.

Example

This example illustrates the use of the event.

private void FpSpread1SaveOrLoadSheetState(object sender, FarPoint.Web.Spread.SheetViewStateEventArgs e)  
{
    if (e.IsSave)
    { 
        Session["SheetName" + e.Index] = e.SheetView.SaveViewState();
    } 
    else
    { 
        e.SheetView.LoadViewState(Session["SheetName" + e.Index]); 
    }
    e.Handled = true; 
}

Handles FpSpread1.SaveOrLoadSheetState 
    If (e.IsSave) Then
