Dynamics CRM 2011编程系列（41）：Portal的制造（二）
Dynamics CRM 2011编程系列（41）：Portal的制作（二）
上篇博文介绍了Portal的数据显示控件，它们分别是：CrmMetadataDataSource，SavedQueryDataSource，XrmServiceContext。那本文来看看在Portal中对CRM的数据进行CRUD。
我们在Portal中对Dynamics CRM 系统中的数据进行CRUD操作可以有两个方向：1.使用ADO.NET直接操作Dynamics CRM 系统的数据库；2.使用Dynamics CRM 系统为制作Portal而提供的前期绑定代码（在上篇博文中使用过）。本文就不介绍第一种方法啦，就来好好琢磨下第二种方法啦！ :D
我们来看个小DEMO吧：
涉及实体
客户
实现需求
1.显示现有客户基本信息
2.能修改客户的基本信息
3.能删除客户
4.能创建客户
