Clone Entity的实现

前言：
   今天终于把Clone Entity的代码写完了。可能还有一些问题。主要是不能一些栏位的值后续的栏位可能用不上.
    技术关键点:
    1.__doPostBack('<%this.Button1.ClientID%>','')实现开启页面以后自动点击按钮的功能。
    2.MS Crm是用SQL2005对.net framework 3.5的功能有一些并不好.UpdatePanel没有用上。所以没有动画效果.
    3.终于知道怎么只编译单一的网页，还有就是发布时会删除发布目录内的内容。要小心一些.
    4.javascript执行时机会慢于Page_Load,不知道window.onload是在什么时机调用的.会先于Page_Load还是后于window.onload.
    5.我是在Page_Load时注册一段script来实现我在window.onload要执行的代码。才实现自动点击按钮的功能.
    6.问个问题就是MS如何实现动态加载网页的。尤其是他的变量和javascript那部分还是不太理解。可能还是要看一下.本来我还想模仿一个MS的办法，但最终还是放弃了.
    7.取父窗口内容的代码还是比较有用的应该要记下来，留备下次使用.
    8.Callback还没有试出来，要试试Callback Events的网页的用法.
    附一部分代码.
