    Re: how to force user to select drop down list item first before continue next in C#

    You can use some jQuery magic to do this:

    $(function() {
        $('#ddlSelectCinema').prop('disabled',true);
        $('#ddlSelectSession').prop('disabled',true);
    });

    This code will disable the "Select Cinema" and "Select Session" drop downs. Then you need an event handler on the drop downs:

    $(function() {
        $('#ddlSelectMovie').change(function() {
            $('#ddlSelectCinema').prop('disabled', false);
        });
        $('#ddlSelectCinema').change(function() {
            $('#ddlSelectSession').prop('disabled', false);
        });
    });

    This will not hide it, but it will disable them. You might want to also add a CSS class called 'disabled' or something and apply and remove that class as you disable/enable the. This way you can style the drop downs and make them look disabled.
