ListBox and Javascript

Ken
I have a ListBox item and I am using a javascript onclick function to
add items to the ListBox. The problem is when I do a post back .net
doesn't see any of the items I added w/ javascript, just the original
items. It there anyway to fix this?

Thanks,

Ken

you will need to extract them from your form post on postback and then then
use them befre form load occurs to make them available. If your loading the
listbox in form load then you will probably be overwriting the values your
javascript has added.
