I've this problem, in my aspx i put a ListBox, when i add lines to this ListBox and and click de button "Guardar", a java script function is called. In that java script I have this code:

                    var lbPozosToAdd    =    document.all.lbPozosToAdd;

            for(var i = 0; i < ListBox.length; i++){
            ListBox.options[i].selected = true;
            }

This work OK, but in the code behind when I try to validate the ListBox Ex: if(ListBox.Items.Count != 0), the count is always 0, why?

Thanks for your help, sorry my English, I'm from Argentina

How are the items added to the ListBox?
