why not fill them "at once" instead of filling them 1 by 1?
you could of course "copy" all the items of the first into all the others, but why loop several times?

The list is result of a query, they are almost 1000 items.

>they are almost 1000 items.

well, that's 2 problems at once.
first of all, that WILL take some time to be loaded: in total 20K items...

secondly, and that's the primary problem: as a user, I would HATE software that let's me choose among 1000 items in a drop-down list !!!!!
much more user-friendly would be some alternative solution, like a filtering text-box, where after typing for example 1-2 characters, the combo/list will fill only those items that match that list. a popup-form would also be nice there...

anyhow, did you already check what part takes the most time, the query, the looping or the filling? what are the timings, btw?

tip: hide the combo box controls while filling, that might help a bit.
