<这个按钮onclick="greettanchushow()"的这个事件是弹出一个窗体，在同时我想获取到相应人的ID。本人想过两个方法：
一，写一个标签把值存到标签里，在后台读取出来。
<asp:Label ID="OppidLabel" runat="server" Text='<%#Eval("hyid") %>'></asp:Label>
这样的话，在后台读取需要循环，获取到的ID同时也不是点击相应人的ID。
二，onclick='greettanchushow(<%#Eval("hyid") %>)'在这里传值，这个方法我写了个JS。想传过去，在JS里面保存到Session里面。但是js没有Session属性.请问如何在点击onclick="greettanchushow()"同时获取相应人的ID。如有表述不详细的地方。请讲...

Answer 1

1。 可以在后台取到这一行的所有数据，然后想取id取id，想取name取name.
e.Row.DataItem as 实体类;
e.Row.DataItem as DataRow;
2.  没看明白

Answer 2

(object sender,eventargs e)
e代表的事件参数

Answer 3

你可以获取到参数了后台调用greettanchushow这个方法。

Answer 4

datalist读取的，不只一个人。这个跟按钮没有任何关联。
