Occurs when an active worksheet in a workbook is about to be changed.
public event ActiveSheetChangingEventHandler ActiveSheetChanging
Public Event ActiveSheetChanging As ActiveSheetChangingEventHandler
The ActiveSheetChanging event's data class is ActiveSheetChangingEventArgs. The following properties provide information specific to this event:
|Cancel||Gets or sets whether the changing the active sheet should be canceled.|
|NewActiveSheetName||Gets the name of the new active worksheet. Inherited from ActiveSheetChangeEventArgsBase.|
|OldActiveSheetName||Gets the name of the old active worksheet. Inherited from ActiveSheetChangeEventArgsBase.|
The ActiveSheetChanging event allows you to perform any actions before an active worksheet is changed. You can cancel changing the active worksheet by setting the event parameter's Cancel property to true.
After an active worksheet has been changed, the SpreadsheetControl.ActiveSheetChanged event is raised.
When a worksheet is removed from the workbook, the ActiveSheetChanging event does not occur, although the SpreadsheetControl.ActiveSheetChanged event is fired.
