You could use some type of ViewState("FLAG") that you look for before
populating the dropdown.  If the ViewState("FLAG") <> False or something
like that you could decide from that.  My understanding of the ViewState()
container is that it's the best way to preserve state between postbacks.
Hope this helps.

Subject: [aspx_professional] DropDownList question

Could someone tell me how I can resolve the following situation.
I have a dropdown that is populated from information in a database. I
populate the list in a sub routine only if a selected button is pressed. The
list only needs to be populated once(1000 records). How do I populate the
list only once? I guess i am trying to mimick the if is not postback used in
a page_load event in a sub routine. Is this possible? Thanks for your help
in advance. Rich.
