请教两个有关服务器控件的问题。

大家先请看下边的代码<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="gb2312" Debug="true" %>
<%@ Import Namespace="System" %>
<%@ import Namespace="System.IO" %>
<script runat="server">
    void Page_load(Object sender, EventArgs e)
    {
    int i;
        for (i = 0; i < 10; i++) {
            Label1.Text += "<asp:RadioButton ID='cname' runat='server' Text='第" + i + "项' />"+i+"<br />";
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Label2.Text = cname.value;
    }
</script><html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Untitled Page</title>
</head>
<body>
    <form runat="server">        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
        <asp:Label ID="Label1" runat="server" Width="123px"></asp:Label>
        <asp:Button ID="Button1" runat="server" Text="递交" OnClick="Button1_Click" />
    </form>

</body>
</html>我想做一个投票程序，在不知道投票项有几项的情况下希望循环显示RadioButton控件，然后显示在Label1中，可是如上面代码得出的结果确不能正常显示RadioButton控件请问是为什么？如果把RadioButton换成<input id="cname" type="radio" runat="server" /> 则能正常显示，但如果执行Button1_Click，则会提示错误，说没有cname这个对象，请问这是为什么？要如何解决，谢谢。

不能这么添加服务器端控件的，你这样把runat=server输出到客户端去了，客户端不认识，或者用数据绑定的方法，或者应该这么做<%@ Page Language="C#" ContentType="text/html" ResponseEncoding="gb2312" Debug="true" %>
<%@ Import Namespace="System" %>
<%@ import Namespace="System.IO" %>
<script runat="server">
const int n = 10;
RadioButton[] rbs;    void Page_load(Object sender, EventArgs e)
    {
rbs = new RadioButton[n];
        for (int i = 0; i < n; i++) {     rbs[i] = new RadioButton();
    rbs[i].GroupName = "cname";
    rbs[i].ID = "cname" + i.ToString();
    rbs[i].Text = "第" + (i+1).ToString() + "项";
    ph.Controls.Add(rbs[i]);
    ph.Controls.Add(new LiteralControl("<BR/>"));
        }
    }    protected void Button1_Click(object sender, EventArgs e)
    {
RadioButton rb = null;
foreach(RadioButton rb2 in rbs)
if(rb2.Checked)
{
rb = rb2;
break;
} if (rb != null)
         Label2.Text = rb.Text;
    }
</script><html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Untitled Page</title>
</head>
<body>
    <form runat="server">        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label><br>
        <asp:Label ID="Label1" runat="server" Width="123px"></asp:Label> <asp:PlaceHolder id="ph" runat="server" />
        <asp:Button ID="Button1" runat="server" Text="递交" OnClick="Button1_Click" />
    </form>

</body>
</html>
数据绑定这么做<%@ Page Language="C#" EnableViewState="true"%>
<%@ Import Namespace="System" %>
<%@ import Namespace="System.IO" %>
<script runat="server">
    void Page_load(Object sender, EventArgs e)
    {
if (!IsPostBack)
{ string[] ss = {"第1项","第2项","第3项","第4项","第5项","第6项","第7项","第8项","第9项","第10项"};
rbl.DataSource = ss;
rbl.DataBind();
}    }    protected void Button1_Click(object sender, EventArgs e)
    { if (rbl.SelectedIndex >=0)
         Label2.Text = rbl.Items[rbl.SelectedIndex].Text;
    }
</script><html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Untitled Page</title>
</head>
<body>
    <form runat="server">        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label><br>
        <asp:Label ID="Label1" runat="server" Width="123px"></asp:Label>
<asp:RadioButtonList id="rbl" runat="server" />
        <asp:Button ID="Button1" runat="server" Text="递交" OnClick="Button1_Click" />
    </form>

</body>
</html>
那如果我想把RadioButton和其他代码混合起来要如何做呢？我这里用Html代码演示一下（asp.net刚开始学不熟，不好意思。）<table width="100%"  border="0" cellpadding="5" cellspacing="1" bgcolor="#666666">
<form name="form1" id="form1" method="post" action="">
  <tr>
    <td colspan="2" bgcolor="#F7f7f7">请选择投票项</td>
    </tr>
  <tr>
    <td width="4%" height="25" bgcolor="#FFFFFF"><input type="radio" name="radiobutton" value="radiobutton" /></td>
    <td width="96%" bgcolor="#FFFFFF">
      投票项一
    </td>
  </tr>
  <tr>
    <td bgcolor="#FFFFFF"><input type="radio" name="radiobutton" value="radiobutton" /></td>
    <td bgcolor="#FFFFFF">      投票项二 GetImages</td>
  </tr>
  <tr>
    <td bgcolor="#FFFFFF"><input type="radio" name="radiobutton" value="radiobutton" /></td>
    <td bgcolor="#FFFFFF">      投票项三</td>
  </tr>
</form>
</table>类似这么一个东西，这里面可能每个项还会加一些代码，比如投票项三的GetImages那里可能会加一个函数显示代表票数的图片，方便的话请讲一下大概的思路，谢谢。
use a datagrid + databinding and this guy's RowSelectorColulmnhttp://www.metabuilders.com/Tools/RowSelectorColumn.aspx
asp.net做这种东西真不方便，asp就省事多了
你这种想法是不对的，一开始总有点不习惯，主要是思路问题，等你学会了ASP.NET，你就知道ASP.NET的威力了
