Autopostback on a remote server

[Lil Ms Squirrel]

I have a questionnaire type web form where if the user selects a particular answer, it shows or hides a textbox for an additional description.

It all works well on my local machine, but when i try to use it from the production server, the postbacks don't seem to work. The progress bar shows it's posting back but the controls don't appear!

Anyone seen this before and know how to fix it?

Cheers

PS I know doing loads of postbacks is a bad idea, but you try telling my boss that

[nemaroller]

post your code (the relevant code)

Okay this is the code.

The entire form is generated dynamically based a set of customised questions from the database.

It now works sporadically for some options, but not for all of them. And each time I try it, only one or two postback properly whereas on my local machine it all works perfectly:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim ds As Questions
        Dim question As Questions.QuestionsRow
        Dim tablenames(0) As String
        Try
            tablenames(0) = "Questions"
            If Not IsPostBack Then
                ds = New Questions
                If PopulateClientData() = False Then
                    'cancel the load because this review has already been completed
                    Exit Sub
                End If
                'populate the dataset and store in the session object
                SqlHelper.FillDataset(connectionString, CommandType.StoredProcedure, "uspGetReviewQuestions", ds, tablenames)
