Changing the contents of an ASP Panel

I have been working on this little problem for weeks and I am becoming highly frustrated.

I have a panel on my page that I want to dynamically change.

I use the following code (Just a snippet);


Select myFlag
Case 1
txt = New TextBox
txt.Width = "300"
txt.Text = "You must Check either Yes Or No here."
txt.ReadOnly = True
txt.ForeColor = Drawing.Color.Red
txt.BackColor = Drawing.Color.Transparent
txt.Font.Size = "12"
txt.Font.Italic = True
txt.Font.Bold = True

pnlSpouseErr.Controls.Add(txt)

End Select


It does not update the panel.

If I take the updating code out of the Select Statement it does the update.

The variable myFlag always will equal 1 and when I step through the code, it seems to run the lines in question but the panel does not update.

Thanks for your help
