实现DataGrid列添加Radio（单选框）列的问题!!!

[wu621]

想实现DataGrid列添加Radio（单选框）列,上网搜索相关的资料.
其中大多的例子都有下面的代码:
Dim js As String
js = "<script>"
js = js & "function ld(){"
js = js & "for(i=0;i<document.getElementsByName('RadioName').length;i++)"
js = js & "if(document.getElementsByName('RadioName')[i].value=="
js = js & "document.getElementById('" & rd.ClientID & "').value) "
js = js & "document.getElementsByName('RadioName')[i].checked=true"
js = js & "}"
js = js & "window.onload=ld;"
js = js & "</" & "script>"
Page.RegisterStartupScript("js", js)
不知道是什么意思??
html 里是 <input type=radio name="RadioName">为什么不是<asp:radio> 呢???
rd.ClientID 是什么意思呢??

<input type=radio name="RadioName"> 客户端代码，这样多用javascript来实现，比较好

<input type=radio name="RadioName">为客户端html控件，更容易实现javascript，
