Event Data

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

PropertyDescription
ColumnGets the column index of the cell that is changed.  
RowGets the row index of the cell that is changed.  
ViewGets the view that contains the cell that is changed.  
Remarks

This event is raised by the OnChange method when the user modifies data in the cell.

For more details on the individual event arguments, refer to ChangeEventArgs members.

This event does not occur if the cell is already in Edit mode when the user double-clicks the cell.

This event is not raised on a paste; the DefaultSheetDataModel.Changed event is raised on a paste though.

Example
This example raises the Change event when the user changes the data in a cell.
fpSpread1.ActiveSheet.SetValue(0, 0, "Change Me");
Label1.Text = "Change the data in the first cell then move focus to another cell.";

private void fpSpread1_Change(object sender, FarPoint.Win.Spread.ChangeEventArgs e)
{
     ListBox1.Items.Add("Change event fired!");
}
Fpspread1.ActiveSheet.SetValue(0, 0, "Change Me")
Label1.Text = "Change the data in the first cell then move focus to another cell."

Private Sub FpSpread1_Change(ByVal sender As Object, ByVal e As FarPoint.Win.Spread.ChangeEventArgs) Handles FpSpread1.Change
     ListBox1.Items.Add("Change event fired!")
End Sub
