为什么我点了前进、后退等按钮还是整个页面都刷新呢？请各位帮帮忙解决，我的要求是局部刷新
C# code:
aspx页贴出一部分
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="False" RenderMode="Inline"
UpdateMode="Conditional">
<ContentTemplate>
<asp:DataList ID="dlrelated" runat="server" RepeatDirection="Horizontal" ShowFooter="False"
ShowHeader="False" Width="100%" RepeatColumns="1" CellSpacing="15">
<ItemTemplate>
Item:<%# DataBinder.Eval(Container,"DataItem.p_xh") %>
</ItemTemplate>
</asp:DataList>
<div style="width: 100%; background-color: #ffaf00; text-align: right; color: bla
