LoginView.ViewChanging Event

Occurs before the view is changed.

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

public event EventHandler ViewChanging
/** @event */
public void add_ViewChanging (EventHandler value)

/** @event */
public void remove_ViewChanging (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

When the LoginView control switches views, it removes the controls from the previous template and creates new child controls from the new template. The ViewChanging event is raised before the previous controls are removed.

Use the ViewChanging event to perform any processing, such as saving control information, necessary before the controls are removed.

NoteNote:

The ViewChanging event is only raised if the login status for a user changes during a postback to the page. The ViewChanging event will not be raised if a user logs in using the Login control, or if the user logs out using the LoginStatus control. The ViewChanging event will also not occur if a user is logged in or out followed by a redirect. An example of when the ViewChanging event will occur is when a user is logged out by calling the SignOut method without being redirected to another page. During the next postback to the page, the LoginView control will detect the change in the login status for the user, and then raise the ViewChanging event.
