Raises the ViewChanged event after the LoginView control switches views.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

protected virtual void OnViewChanged(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs object that contains the event data.

When the LoginView control switches views, it removes the controls from the previous template and creates new child controls from the new template. The OnViewChanged method is called after the new child controls are created.

Use the OnViewChanged method to perform any processing, such as data binding, necessary to initialize the controls on the new view.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnViewChanged 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 OnViewChanged in a derived class, be sure to call the base class’s OnViewChanged method so that registered delegates receive the event.
