ClientFormsAuthenticationMembershipProvider.UserValidated Event

Occurs when the user is validated.

Namespace:  System.Web.ClientServices.Providers
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

'Declaration
Public Event UserValidated As EventHandler(Of UserValidatedEventArgs)

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 UserValidated event to display intrusive UI. For example, you should not use the UserValidated event to display a welcome dialog box.

The following example code demonstrates how to use this event to display the user name in the title bar of a form.

Private WithEvents formsMembershipProvider As  _
    ClientFormsAuthenticationMembershipProvider = _
    System.Web.Security.Membership.Provider

Private appName As String = "ClientAppServicesDemo" 

Private Sub Form1_UserValidated(ByVal sender As Object, _
    ByVal e As UserValidatedEventArgs) _
    Handles formsMembershipProvider.UserValidated

    ' Set the form's title bar to the application name and the user name. 
    Me.Text = String.Format("{0} ({1})", appName, e.UserName)

End Sub
