asp:LinkButton的PostBackUrl傳參，“服務器標記的格式不正確”

<div>
    <asp:LinkButton CssClass="btn" ID="lbtnExport" CommandArgument='<%#Eval("id") %>' PostBackUrl="<%#"/BusinessManage/Shop/ExportExcelOther.ashx?systemType=1&id="+Eval("id") %>" Visible="false" CommandName="export" runat="server">導出</asp:LinkButton>
</div>

解決：

lbtnExport.PostBackUrl = "/BusinessManage/Shop/ExportExcelOther.ashx?systemType=1&id=" + orderid;
