i got this code modification:

columns.template(@<text><input name="chkstatus" type="checkbox" class="chkformols" /></text>) .headertemplate("<input type='checkbox' id='chkselectall' onclick='checkall(this)' />").width(50);    function checkall(ele) {             debugger;             var state = $(ele).is(':checked');             var grid = $('#grid').data('kendogrid');             if (state == true) {                 $('.chkformols').prop('checked', true);             }             else {                  $('.chkformols').prop('checked', false);             }         };
