Initializing a textbox or label from Page_Load

I'm trying to initialize some text from the page_load routine, but it doesn't display any text, and I'm unsure why. Here is my code, tell me what you think:


<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="GeneralControl.ascx.vb" Inherits="WebApplication2.GeneralControl" %>
<script runat = "server">
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
GENUPDATE.DataFile = "C:\WEB_ROOT\Login\GENERAL.xml"
GENUPDATE.XPath = "/root/GENERAL"

Dim linkbutton1 As New LinkButton
Dim linkbutton2 As New LinkButton
Dim labelupdate2 As New TextBox
Dim labelupdate3 As New TextBox
Dim Vnum As String
...
