HyperLink 嵌在 DataList 出問題！已經搞定

<asp:DataList id="DataList1" runat="server" RepeatColumns="3" RepeatDirection="Horizontal" CellSpacing="5" CellPadding="5" Width="247px" Height="142px">
                        <HeaderTemplate>
                            <FONT face="宋體">
                                <P>
                                    <asp:Label id="Label1" runat="server" Width="84px" ForeColor="Brown">圖書分類列表</asp:Label>
                                    <br>
                                    -------------
                                </P>
                            </FONT>
                        </HeaderTemplate>
                        <ItemTemplate>
                            <asp:HyperLink id="HyperLink1" Text='<%# DataBinder.Eval(Container.DataItem,"LeiBieMC")%>' NavigateUrl="<%#"list.aspx?typeid="+DataBinder.Eval(Container.DataItem,"IDs")%>" runat="server">
                            </asp:HyperLink>
                        </ItemTemplate>
                        <SeparatorTemplate>
                            <FONT face="宋體"></FONT>
                        </SeparatorTemplate>
                    </asp:DataList>

居然不能轉到檢視狀態，問題出在NavigateUrl後面的值。提示以下的錯誤資訊：

“未能在設計檢視中開啟，"<%…"值"…%>" 塊中，以不同方式將值括起來 ”
