Dynamics CRM 2011 编程系列(32):Ribbon的开发2（按钮的禁用规则）

Dynamics CRM 2011 编程系列(32):Ribbon的开发二（按钮的禁用规则）

     在上篇博文里介绍了如何在Dynamics CRM 2011系统中添加Ribbon按钮。但现实的需求往往都比较的复杂，它们都涉及了按钮的禁用技术。Dynamics CRM 2011为我们提供了2种按钮禁用技术：一、使用DisplayRule；二、使用EnableRule。

    DisplayRule和EnableRule的区别：使用DisplayRule可以彻底的将按钮在Ribbon中隐藏，DisplayRule是在服务器端执行的；使用EnableRule可以将按钮禁用但是依然显示，禁用的逻辑是通过JS来控制的，所以EnableRule是在客户端执行的。

   我们来看几个例子吧：
