我没有在Page_Load（对象发送者，

我认为使用服务器控件可能更容易，否则对于

大部分服务器甚至不知道它存在。

根据您的需求可能是最好的解决方案。


即使你去了服务器重新创建html控件的路线<每次加载/回发时，
将需要尽可能多的服务器功率。因为它只需要使用服务器控件

System.EventArgs e）更改此html值的功能

变量...

< blockquote>

根据要求，在我的情况下这可能是不可能的....任何

身体都有以下任何一个想法：

1）检查服务器控制radiobutton是否检查，使用

javascript，每次加载页面....如果你知道告诉我所有步骤

需要采取。

2）或者从内部更改隐藏的html变量的值c＃
我们在asp.net网站上写的
代码....

I think it might be easier just to use a server control becuase otherwise for
the most part the server doesnt even know it exists.
Depending on your needs that might be the best solution.

even if you went the route of having the server re-create the html control
on each load/postback it would take as much server "power" as it would to
just use a server control

as per requirments this might not be possible in my case....Does any
body has idea at any one of the following:
1) To check if a server control radiobutton checked or not , using the
javascript, each time page is loaded....If u know tell me wht all steps
need to be taken.
2) or to change the value of a hidden html variable from inside the c#
code that we write in asp.net website....
