    $("button").on("click", function () {
        var code = $(this).attr('id');        
        $.ajax({
            url: '/ajaxExecute.aspx?Fn=GETUSERFORUPDT',
            type: 'POST',
            context: document.body,
            data: 'Code=' + code,
            cache: false,
            success: function (response) {
                if (response != 'undefined') {
                    window.location = 'AddEditUser.aspx';
