The issue is changes in a dropdown box will require the app to perform
a DB lookup.
If the user changes a dropdown box, how can one tell the system to
postback and then what caused that postback. Unless you session all
of the vars or keep a hidden version of each, then you need to set
some switch to tell the system what occurred!
I will say this is MUCH easier in ASP.net.
