[RESOLVED] validate insertion via a javscript/jquery or code behind

i have certain validation check via a jquery/javascript in asp.net 3.5 vb.net

Code:

---

<script type="text/javascript">

        $(function() {
            $('#<%= btn_submitt.ClientID %>').click(function() {

                valid = true;
                var checkedControls = $('#<%= CheckBoxList1.ClientID %>').find('input:checkbox:checked');
                var selected = jQuery('#<%= Rdbtn_hotelbook.ClientID %> input:checked').val();

                if (checkedControls.length == 0) {

                    alert('Please select atleast one checkbox from Company Type');

                }
                else if (selected == 0) {
                    var checkedControls1 = $('#<%= hotel_requirement_Types.ClientID %>').find('input:checkbox:checked');

                    if (checkedControls1.length == 0) {

                        alert('Please select atleast one from hotel requirement');

                    }

                 
                    //            alert('u need to explore placeholder');

                }

            });


            return false;


        });   
     
      </script>

and on submitt button i have following code (see my next post in same thread)

it is validation through jquery/javascript but when it comes to code behind it insert when else conditon is true . now the problem is that i want to pass certain variable from jquery/javascript to code behind to validate that u can isnert to tables(mind that i am inserting stuff to multiple table) the main table is users .and it returns userid and i insert into another tables by using same userid.

i hope i m quite clear about my problem if it is still not please post me back
