MultiView::OnActiveViewChanged Method

Raises the ActiveViewChanged event of a MultiView control.

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

protected:
virtual void OnActiveViewChanged(
	EventArgs^ e
)

Parameters

e
Type: System::EventArgs
A System::EventArgs that contains the event data.

The ActiveViewChanged event is raised when the active View control within a MultiView control changes between posts to the server, and you can provide a custom handler for this event.

Raising an event invokes the event handler through a delegate. For more information, see How to: Consume Events in a Web Forms Application.

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

The following example demonstrates how to specify and code an event handler for the ActiveViewChanged event of a MultiView control. When the active view changes, a message is displayed in a Label control on the page.

NoteNote

The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information on the Web Forms code model, see ASP.NET Web Page Code Model.
