                 this.innerHTML = "<input type='checkbox' id='chkHeader'  />";
             }
         });
         $('#gridContent table th input:checkbox').click(function (e) {
             var table = $(e.target).closest('table');
             $('td input:checkbox', table).attr('checked', e.target.checked);
