Repeater中嵌套RadioButton和CheckBoxList

昨天做个项目，其中有个页面，Repeater中要嵌套RadioButton和CheckBoxList，参照别人的方法，但就是取不到RadioButtonList的SelectedValue，弄了一个晚上才发现，绑定数据的时候没有放在!IsPostBack中，郁闷。代码如下
aspx
----------------------------------------------------

 1<asp:repeater id="Rt_One" Runat="server">
 2                                    <ItemTemplate>
 3                                        <tr>
 4                                            <td valign="top">
 5                                                <asp:TextBox ID="txtquest" Runat="server" Text='<%# DataBinder.Eval( Container.DataItem ,"[questionid]") %>' Width="0">
 6                                                </asp:TextBox>
 7                                                <asp:Label ID="lblQuest" Runat="server">
 8>

 1<asp:repeater id="Rt_More" Runat="server">
 2                                    <ItemTemplate>
 3                                        <tr>
 4                                            <td valign="top">
 5                                                <asp:TextBox ID="txtQuest2" Runat="server" Text='<%# DataBinder.Eval( Container.DataItem ,"[questionid]") %>' Width="0">
 6                                                </asp:TextBox>
 7                                                <asp:Label ID="lblQuest2" Runat="server">
 8>

cs

1private void Page_Load(object sender, System.EventArgs e)
2        }

 1private void RtRt_OneBind()
 2        }

 1private void Rt_MoreBind()
 2        }

 1override protected void OnInit(EventArgs e)
 2        }

 1private void Rt_One_ItemDataBound(object sender, RepeaterItemEventArgs e)
 2        }

 1private void Rt_More_ItemDataBound(object sender, RepeaterItemEventArgs e)
 2        }

 1private void Button1_Click(object sender, System.EventArgs e)
 2        }

绑定的代码不是我写的，有点乱。
