        {
           var chkall = document.getElementById(chkboxAllID);
           
           var chkother = document.getElementsByTagName("input");
           
           for (var i = 0; i < chkother.length; i ++ )
           {
              if( chkother[i].type == 'checkbox')
              {
                 if(chkother[i].id.indexOf(controlid) > - 1)
                 {
                    if(chkall.checked == true)
                    {
                       chkother[i].checked = true;
                    }
                    else
                    {
                       chkother[i].checked = false;
                    }
