asp.net 中RadioButtonList控件问题，如何判断是哪条记录的？
正在做一个调查投票的小功能，碰到如下问题当提交时，需判断是否都给了分数，如果没给分，给出提示“1.1未打分”这个投票问题我用的是repeater控件绑定的。如下：

  <table class="table1">

                                    <asp:Repeater runat="server" ID="rptItemlist">

                                        <ItemTemplate>

                                            <tr>

                                                <td class="td1">

                                                    <span style="color: #FF001E">*</span>

                                                        <%#Eval("sn")%>

                                                </td>

                                                <td class="td2">

                                                    <span>

                                                        <%#Eval("ItemTitle")%></span>

                                                </td>
