SessionID to appear on the form

[Kevin Davis]

I have created a text box on my form and the codebehind is as follow:
Dim NID As String
Dim justid As String

NID = User.Identity.N ame
justid = NID.Substring(7 )
TextBox1.Text() = UCase(justid)
Session("Networ kID") = justid

I'm not receiving any errors nor is the sessionID is appearing on the form, what could I be doing wrong? I'm using Microsoft Visual Basic .NET 2003.
