最近折腾SharePoint 2010 比较多，有些客户想定制EditPeople控件，有些领导感觉那个搜索不太“好”，希望能有一个树形选择就完美了

哎，客户有要求，咱们哪里能不办？

        //sDialogUrl = "/_layouts/CustomPeopleEditor/CheckUsesr.aspx?IsDlg=1";
        var sFeatures = 'resizable=yes,status=no,scrollbars=no,menubar=no,directories=no,location=no,width=470,height=530px';

        var rv = commonShowModalDialog(sDialogUrl, sFeatures, Callback_User);
    }
</script>

如果我们把 sDialogUrl = sDialogUrl + '&DefaultSearch=' + escapeProperly(defaultSearch);

换成  sDialogUrl = "/_layouts/CustomPeopleEditor/CheckUsesr.aspx?IsDlg=1";

就会调出我们自己写的treeview控件

 首先动态调用_Dialog_UserCheck 这个函数，然后根据Callback_User回写value

当然要完美实现这一应用，可能还需要额外的代码，作为Demo代码可能已经够了，核心函数都在这里·
