public void CancelUpdate()


Calling the ChartCollectionBase.BeginUpdate method locks a ChartCollectionBase instance to prevent any change notification events from being fired in response to any of its properties being changed. The code performing multiple changes must be enclosed within BeginUpdate/EndUpdate or BeginUpdate/CancelUpdate method calls.

Calling the CancelUpdate method after a call to the ChartCollectionBase.BeginUpdate method unlocks the ChartCollectionBase object but doesn’t raise any change notifications. To unlock the collection object and raise all the notification events, call the ChartCollectionBase.EndUpdate method.
