使用DataList时出现问题

<asp:DataList ID="dlCardTitle" runat="server" Width="336px" Font-Size="9pt">
                        <ItemTemplate>
                        <table style="width: 478px" cellpadding="0" cellspacing="0">
                                <tr>
                                    <td style="width: 478px; text-align: left; background-image: url(../Admin/Image/标头.jpg); text-indent: 3pt; height: 22px;">
                                       <asp:Label id="labCardTitle" ForeColor="Black" runat="server" Font-Size="9pt" Text="帖子标题：" />
                                    <a href='CardPartInfo.aspx?title=<%# DataBinder.Eval(Container.DataItem,"title") %>' style="text-decoration:none">
                                    <%# DataBinder.Eval(Container.DataItem, "title")%></a>
                                    </td>
                                    </tr>
                                     <tr>
                                    <td style="width: 478px; text-align: right; background-image: url(../Admin/Image/时间.jpg); height: 22px;">
                                        <asp:Label ID="Label3" runat="server" Font-Size="9pt" Text="发帖日期："></asp:Label>
                                  <asp:Label ID="labCardDate" runat="server" Height="1px" Text='<%# DataBinder.Eval(Container.DataItem,"title_uptime") %>' Font-Size="9pt"></asp:Label>&nbsp;&nbsp;
                                    </td>
                                </tr>
                            </table>
                        </ItemTemplate>
                    </asp:DataList>
出现的问题是：DataBinding:“System.Data.DataRowView”不包含名为“title”的属性。请提供一下帮助 先谢了！
