       </script>


    <form id="form1" runat="server">

I can not see exactly what is causing your problem, but what I can see is that you are using cbList as the name which is a server side name. Instead you should use cbList.ClientID which is a unique client side name for the control. In other words add the onclick event side like this:

chkAll.Attributes["onclick"] = string.Format("jqCheckAll2(this.id, '{0}')", cbList.ClientID);

then change jqCheckAll2 to this:

       function jqCheckAll2(id, name) {
           $("#" + name).find(":checkbox").attr('checked', $('#' + id).is(':checked'));
       }

Use the checkbox to check all or uncheck all for all the active checkbox inside a div. ClientIDMode="Static" just doesn't allow the ID change when running on server.

<asp:CheckBox ID="chkAll" runat="server" ClientIDMode="Static"/>
    <asp:Label ID="lblAll" runat="server" Text="Label" ClientIDMode="Static">Select All</asp:Label>

    $(document).ready(function() {
        $("#chkAll").on('change', function() { // on change of state        
            if (this.checked) // if changed state is "CHECKED"
            {
                $("#lblAll").text("Unselect All");
                $("#myDiv input[type=checkbox]").each(
                    function() {
                        if($(this).attr('disabled')==null)
                          $(this).prop('checked', true);
                    }
                );
            } else {
                $("#lblAll").text("Select All");
                $("#myDiv input[type=checkbox]").each(
                    function () {
                        if ($(this).attr('disabled') == null)
                           $(this).prop('checked', false);
                    }
                );
            }
        });
    });
