Imports System.Text
Public Class locker
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Request.IsAuthenticated Then
            WelcomeBackMessage.Text = "Welcome back!"
        

             AuthenticatedMessagePanel.Visible = True
            AnonymousMessagePanel.Visible = True
        Else
            AuthenticatedMessagePanel.Visible = False
            AnonymousMessagePanel.Visible = True
        End If

        Dim ident As FormsIdentity = CType(User.Identity, FormsIdentity)
        Dim authTicket As FormsAuthenticationTicket = ident.Ticket
        WelcomeBackMessage.Text = "Welcome, " & User.Identity.Name & "!"

    End Sub

There is noting like pop-up in asp.net. You need to write in response stream for that. — शेखर, Sep 29 '14 at 10:19

If you want to pop-up the message box, just add this to the button code:

onclientclick="javascript:alert('Congratulations!');"

Or in the code behind:

Response.Write("<script language=""javascript"">alert('Congratulations!');</script>")
