如何利用ASP.NET AJAX 1.0对MultiView 里的内容进行AJAX化的显示（请进来看我的代码）

我用了一个<asp:menu>来控制 MultiView1.ActiveViewIndex ，代码在后台代码里。

<form id ="form1" runat="server">
<div >
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>

<asp:Menu ID="Menu1" OnMenuItemClick="Menu1_MenuItemClick"  Orientation="Horizontal"  runat="server" >
    <Items>
        <asp:MenuItem Text="最近" Value="View1" ></asp:MenuItem>
        <asp:MenuItem Text="最热" Value="View12"></asp:MenuItem>
    </Items>
</asp:Menu>
</div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
   <ContentTemplate>
<asp:MultiView ID="MultiView1" runat="server">

<asp:View ID="View1" runat="server">
<................................>
</asp:View>
<asp:View ID="View2" runat =server>
<.........................>
</asp:View>
</asp:MultiView>

</ContentTemplate>
   <Triggers>
   <asp:AsyncPostBackTrigger ControlID="Menu1" EventName="MenuItemClick" />
   </Triggers>
    </asp:UpdatePanel>

</form>

编译运行页面，发现点MENU后，页面还是重新刷新。。不知何故。

aspx:

<table>
  <tr>
  <td>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

    <ContentTemplate>
    <DIV style="WIDTH: 400px; HEIGHT: 500px; TEXT-ALIGN: center">

cs:

    protected void LinkButton1_Click(object sender, EventArgs e)
    {
        MultiView1.ActiveViewIndex = 0;
    }
    protected void LinkButton2_Click(object sender, EventArgs e)
    {
        MultiView1.ActiveViewIndex = 1;
    }
