Problem with a ListBox populated from javascript

Question

Hello, First of all, excuse-me for my poor English... I have a big problem with my ListBox which is populated from javascript. When I do a PostBack in order to update my database the ListBox values are lost. I tried to do something with ViewState = true for my page and listboxes but it doesn't seem to work. Have you got any ideas how to post back the values of my listbox to the server? Thanks in advance. durtal
