LoginView.OnViewChanging Method (EventArgs)
Assembly: System.Web (in System.Web.dll)
When the LoginView controls switches views, it removes the controls from the previous template and creates new child controls from the new template. The method is called before the previous controls are removed.
Use themethod to perform any necessary processing, such as saving control information, before the controls are removed.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
Themethod 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 overridingin a derived class, be sure to call the base class’s method so that registered delegates receive the event.
