Assembly: System.Web (in system.web.dll)
The OnModeChanged method is called by the FormView control to raise the ModeChanged event. It is generally used by control developers when extending the FormView class.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnModeChanged 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 OnModeChanged in a derived class, be sure to call the base class's OnModeChanged method so that registered delegates receive the event.
