c# - 将单选按钮列表添加到 ascx

Question

我想将一个 rsionbuttonlist 添加到我的 ascx web 控件中。我一直收到一个错误，需要将 radionbuttonlist 放在一个标签中。有没有解决的办法？

"
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="step2.ascx.cs" Inherits="ascx_step2" %>
<div id="step2" runat="server">
     <asp:RadioButtonList id="answers" runat="server">       
     </asp:RadioButtonList>
<div>
"

后面的代码:

 ListItem item = new ListItem("a", "a")
   answers.Items.Add(item);

错误:

radiobutton 类型的控件“ctl_00...”必须放置在带有 runat=server 的表单标签内
