How to auto-update field w/ dropdown selection

[slybitz]

So I have a dropdown box that I have filled with two values: AFD, CFD. All I'm trying to do is to get a text box (txtComp) to change its value to that of a dropdown list box (cmbCompany) selection. For some reason I cannot get the text box to reflect this data. I can't even get the text box to just say "CFD" like below with an index change in the dropdown box (which is initially set to "AFD" onload). When I run the debugger and change the dropdown box's values it never recognizes that the "cmbCompany_SelectedIndexChanged" sub (below) is never even initiated. Am I missing something? What all do I need to do to make the txtComp value change to that of the dropdown box on an index change? Thanks for your help!

So your saying that the selected index change event isn't firing? Thats odd, i'm pretty sure it is. I litererally just tried this and it works fine. Just out if interest why is the event handler public, they are normally private?

I got the SelectedIndexChanged to fire but my Me.txtComp.Text won't update with the correct value. No matter if I change the dropdownlist to CFD my code is filling
Me.txtComp.Text value with AFD always. Here's my code:

I figured it out. I needed to wrap my Page_Load code in

If Not IsPostBack Then
   .. code
End if
