AJAX Toolkit Accordion Pane & TextBox Text

I am using the AJAX Toolkit's Accordion control in a project.

In the first pane, I have an UpdatePanel.  Within that UpdatePanel is an HTML table with several TextBox Controls that receive data from a database via a class, "Profile," I have created.  The table also has a Button control which, when clicked, should update the database with the values in the TextBoxes, via the Profile class.

In the page's page_load event, I successfully target and set the values of the TextBoxes from the custom class, "Profile".

The trouble occurs when I attempt to update the database with the Button's Click event handler.  Within this event handler, I set the Profile class' properties with the values from the TextBoxes.  Strangely, the TextBox.Text properties for all of the TextBoxes return exactly the same text that was set during the Page_Load event -- NO CHANGES TO THE TEXT WITHIN THE TEXTBOXES ARE REFLECTED WHEN THE BUTTON IS CLICKED.

This is not a database issue.  I have used the debugger to step through my code and the TextBox.Text property for each of the TextBoxes has been checked.  It is the same text as originally set in the TextBoxes during the Page_Load event, and not the actual text present when the button is clicked.

Experts, any ideas as to what I'm doing incorrectly?

Yes, I've seen that link.  It was the page I used as reference when I initially created the Accordion control on my page.  Unless I missed it, it does not cover my issue.

For some reason, the TextBoxes within the accordion control are not registering any updated text, beyond what was initially set in the Page_Load event, when the Button's Click event is raised.

I solved the problem after much Googling.

Because the controls I was attempting to access resided in an AJAX UpdatePanel, the Page_Load event was being fired before the Button_Click event containing the code for retrieving and updating the values in the TextBoxes.  Therefore, the fields were being re-populated with the original values from the database before the SQL Update command was being issued.  That is why the fields appeared to not reflect changes made prior to the button click.

My ultimate solution was to place the code filling the TextBoxes in the Page_Load event into an IF statement checking if the page was experiencing a postback.  Hence:

Protected Sub Page_Load(Byval sender as Object, byval e as System.EventArgs) Handles Me.Load
     If Not Page.IsPostBack Then
          PopoulateFields()
     End if
End sub
