Using callback, I fill dorpdownlist without postback but it gets empty when a postbac

Hi all!

In a my simple project I use callback to fill a dropdownlist with xml data
returned by a web service, based on a value which is input via another
dropdownlist.

NOTE: I can't use ajax/atlas.

Using javascript and callback all works... but if I press a button or any
event that raise a postback, the dropdownlist that I fill gets empty!

This also if I set its EnableViewstate property to false.

Someone can help me?

Thank you and regards
F.
