Occurs when the user is validated.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
This event occurs only after the user is successfully validated. You can use this event to update your application to reflect the current user. For example, you can use the UserValidatedEventArgs::UserName property to display the user name in your application user interface (UI).
You can silently revalidate users by calling the ClientFormsIdentity::RevalidateUser method. Therefore, you should avoid using the event to display intrusive UI. For example, you should not use the event to display a welcome dialog box.
