我的任务
分享C#中有没有类似showModalDialog的东西，或者说c#怎么和Javascript代码进行通信
写了很多的东西，特效希望用Javascript来写
但是很多的数据是要从C#中提取的
我现在不会让他们进行通信
请教了

用类似以下代码就可以：
Page.RegisterStartupScript("MsgBox", "<script language=javascript> alert('你点击了按钮!')</script>");
格式:
Page.RegisterStartupScript(key, "<script language=javascript>
脚本代码 </script>");
Page.RegisterStartupScript("MsgBox", "<script language=javascript> alert('你点击了按钮!')</script>");
格式:
Page.RegisterStartupScript(key, "<script language=javascript>
脚本代码 </script>");

1.如果希望结构化比较好(三层结构)，可以采用WebService的方法，Ms出了一个WebService.htc，它可以解决你这个问题。但是这种方法你必须提供WebService的服务器段。
2.如果要简单，可以使用不可见的IFrame,有IFrame内的叶面负责数据载入工作。
这样两种方法主要考虑OnClick不会导致叶面重画。

我提供的是一个服务器端的按钮
我希望电击他之后调用一段Javascript代码
并且把运行的结果返回给客户端
Javascript代码调用showModalDialog,谈出另一个叶面
在塔利便可以进行一些操作

你说的是客户端IE组件调用的还是ASP.NET的服务器调用？

服务器端的按钮,可以进入html编辑区中,写onclick事件
这样就可以在客户端调用
