Method OnClosing| Improve this Doc View Source
Raises the Closing event.
protected virtual void OnClosing(CancelEventArgs e)
An System.ComponentModel.CancelEventArgs that contains the event data.
This method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
When overriding in a derived class, be sure to call the base class's method so that registered delegates receive the event.
