如何取出panel里的Radion里的值
我动态生成了一些RadionButtonList代码是这样的：string str1=ds2.Tables[0].Rows[0]["A"].ToString
string str2=ds2.Tables[0].Rows[0]["B"].ToString();
string str3=ds2.Tables[0].Rows[0]["C"].ToString();
string str4=ds2.Tables[0].Rows[0]["D"].ToString();
RadioButtonList rad=new RadioButtonList();
rad.Items.Add("A:"+str1);
rad.Items.Add("B:"+str2);
rad.Items.Add("C:"+str3);
rad.Items.Add("D:"+str4);
rad.ID="rad"+m.ToString();
this.Panel1.Controls.Add(rad);
运行后当我点A选项的时候能够取出A的值 如何实现？在panel里把控件的值取出来
--------------------编程问答-------------------- this.Panel1.Controls[0].Text ? --------------------编程问答-------------------- 我知道可以用Panel1.FindControl取的，但是语法是怎么样的？我要取出RadionButtonList的选项的值 --------------------编程问答--------------------

rad.Items.Add("B:");
rad.Items.Add("C:");
rad.Items.Add("D:");
rad.ID = "rad";
rad.AutoPostBack = true;//设置向服务器提交
this.Panel1.Controls.Add(rad);
rad.SelectedIndexChanged += new EventHandler(rad_SelectedIndexChanged);
}
void rad_SelectedIndexChanged(object sender, EventArgs e)
{
RadioButtonList rad =(RadioButtonList)Panel1.FindControl("rad");
Response.Write("你选择的是：" + rad.SelectedValue);
}
}
--------------------编程问答-------------------- 上面的就行。
aspx页面代码如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Index.aspx.cs" Inherits="Index" %>

<form id="form1" runat="server">
<div>
<asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px">
</asp:Panel>
