Those would be reasons number 4, 7, and 16 for the creation of
EasyListBox :) No viewstate necessary for selection persistence, a
comma-delimited string available by default, and you can specify
dropdown/listbox/combo at run time (for your question on the other
thread).
By the way, if for some reason you want to re-bind your listbox
-- for example, to get the most current data or if you have a long list
and don't want to post all that junk back to the server -- you can
disable Viewstate, grab Request.Form("listBoxName"), and re-select the
item(s) after you databind.'
Cheers,
Peter

I would wager you are rebinding the list when you load the control,
which always happens on postback. You need to wrap the code to bind the
list in an If...Then block, something like...
If Not Page.IsPostBack then
'Code or call to bind list
End if
