Repeater控件中如何用后台代码获取改行对象的某一个属性的值?
HTML code
<asp:Repeater ID="Repeater1" runat="server" onitemdatabound="Repeater1_ItemDataBound">
                <ItemTemplate>
                    <table style="text-align:left;width:800px">
                        <tr">
                            <td style="width:10%"><h4><%# Container.ItemIndex + 1%></h4></td>
                            <td style="width:90%"><h4><asp:HiddenField ID="HF1" runat="server" Value='<%#Eval("题号")%>'/><%#Eval("内容")%></h4></td>
                        </tr>
                        <% string type = %><%#Eval("类型")%><%
                           if (type == "单选"){
                        %>
                        <tr>
                            <td style="width:10%"></td>
                            <td style="width:90%">
                                <asp:RadioButtonList ID="RadioButtonList1" runat="server" DataTextField="内容" DataValueField="选项" />
                            </td>
                        </tr>
                        <%  }else if (type == "多选"){ %>
                        <tr>
                            <td style="width:10%"></td>
                            <td style="width:90%">
                                <asp:CheckBoxList ID="CheckBoxList1" runat="server" DataTextField="内容" DataValueField="选项" />
                            </td>
                        </tr>
                        <%  }else{ %>
                        <tr">
                            <td style="width:10%">答案:</td>
                            <td style="width:90%"><asp:TextBox ID="TextBox1" runat="server" Width="98%"></asp:TextBox></td>
                        </tr>
                        <%  } %>
                    </table>
                </ItemTemplate>
            </asp:Repeater>


C# code

    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        Topic topic = e.Item.DataItem as Topic;
        switch (topic.类型)
        {
            case "单选":
                RadioButtonList rpt1 = e.Item.FindControl("RadioButtonList1") as RadioButtonList;
                rpt1.DataSource = topic.选项;
                rpt1.DataBind();
                break;
            case "多选":
                CheckBoxList rpt2 = e.Item.FindControl("CheckBoxList1") as CheckBoxList;
                rpt2.DataSource = topic.选项;
                rpt2.DataBind();
                break;
            default:
                break;
        }
    }



生成的时候有问题 <% string type = %><%#Eval("类型")%><% 这句话报错,谁能指正一下
谢谢

------解决方案--------------------
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{

}
}
