怎么获取Repeater中RadioButton选中的值

xxx.aspx 页面
<head runat="server">
    <title></title>
    <script type="text/javascript">        
    window.onload = function() {
            var radio = document.getElementsByTagName("input");
            for (var i = 0; i < radio.length; i++) {
                if (radio[i].value == "RB_Test") {
                    radio[i].name = "test";
                }
            }
}    </script></head>        <asp:Repeater ID="Repeater2" runat="server">
                <ItemTemplate>
        <tr>
            <td align=center>
                <asp:RadioButton ID="RB_Test" Text='<%# Eval("Name") %>' runat="server" />            </td>
            <td align=center><%# Eval("Name") %></td>
            <td align=center><%# Eval("Dec") %></td>
            <td align=center><%# Eval("Price") %></td>
        </tr>
        </ItemTemplate>
</asp:Repeater>这样绑定之后能成功 也能现实单选 但是我怎么去获取选中的值？

                    }

            }
      

  2.   

    if (RBtn.Checked)
    {
        name = RBtn.Text;
        break;   //加个break
    }
