Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnClosing method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnClosing(ToolStripDropDownClosingEventArgs) in a derived class, be sure to call the base class's OnClosing(ToolStripDropDownClosingEventArgs) method so that registered delegates receive the event.
