I am writing a user information update page and I populate the form on
Page_Load with the current values of the user's name, etc. When I
change the text in one of the textbox controls (e.g., change the
user's middle initial from M. to X.) and submit the form, the value
seen for middleinitial.text in the Public Sub that is executed when
the Update button is clicked is the initial value (M.) and not the new
value (X.). Is there something I need to do to make the codebehind
file see the new value and not the one set up in Page_Load?
Here are code snippets from register.aspx and register.aspx.vb. Note
that I am using Visual Studio .NET as my development tool.
Code from register.aspx:

Dim cn As SqlClient.SqlConnection
Dim cmd As SqlClient.SqlCommand
Dim prm As SqlClient.SqlParameter
Dim DBError As String
Dim UserID As Integer

Dim PersonalizationCookie As New HttpCookie("UserID")
' At this point, a Response.Write(MiddleInitial.Text) gives the
original value of "M.",

cn = New SqlConnection("Data Source=(local);Initial
Catalog=ArachnidWebWorks;Integrated Security=SSPI;")
cmd = New SqlCommand("spInsertNewUser", cn)
cmd.CommandType = CommandType.StoredProcedure
<remaining code to execute the sproc, etc.>
Any advice is welcome here.
Thanks,
Paul
