首次加载后，页面正常显示，单击菜单标题后，所有都收缩，不显示下面的树形菜单，无法展开。另外那个向左的箭头也不起作用。

前台代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Menu.aspx.cs" Inherits="WEB.Menu" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>
</head>
<body>
<form id="form1" runat="server">
<x:PageManager ID="PageManager1" runat="server" AutoSizePanelID="RegionPanel1" />
<x:RegionPanel ID="RegionPanel1" runat="server" AutoScroll="True" ShowBorder="false">
<Regions>
<x:Region ID="Region1" runat="server" Position="Left" ShowHeader="true" Split="true" Title="管理导航"
Width="200px" BodyPadding="0 0 5 0" BoxConfigPadding="0 0 5 0" BoxConfigPosition="Left"
AutoScroll="True" EnableAjax="true" EnableCollapse="true" EnableSplitTip="true" CollapseMode="Mini" AutoHeight="True">
<Items>
</Items>
</x:Region>
</Regions>
</x:RegionPanel>
</form>
</body>

找了好久，有类似的问题，但不是我这个问题，我真不知道原因在哪里了

找到第一个问题：accpan.Layout = FineUI.Layout.Fit;忘记设置了。
