If you are trying to have linked drop downs, the best way to do it is to have a script that returns the a prebuilt select box and an AJAX call that requests it.

Here is the documentation for jQuery's Ajax method if you need it.

$(document).ready(function(){

    $('#countrylist').change(function(e){
        $this = $(e.target);
        $.ajax({
            type: "POST",
            url: "scriptname.asp", // Don't know asp/asp.net at all so you will have to do this bit
            data: { country: $this.val() },
            success:function(data){
                $('#stateBoxHook').html(data);
            }
        });
    });

});

Then have a span around your state select box with the id of "stateBoxHook"
