怎样使页面刷新后保存保持Ul菜单展开
我把左边的菜单写成了用户自定义控件，然后放到母版页里面去，
当点击子节点，显示相关数据在右边，同时页面会刷新（整个母版页都刷新了）
刷新后，子菜单收起来了，我需要它还是展开的。我用什么方法可以使得菜单在刷新后，仍然保持展开状态？
我不是使用的treeview,而是使用的Repeater。而子菜单连接到右边的数据，是通过
<ahref="<%=Dir %>default.aspx?id=<%#Eval("ItemCategoryID") %>">XXX</a>
[解决办法]
我记得treeview有一个属性ExpandAll(); 可以展开所有子节点，你反编译下，看看如何实现的

帮顶一下！！
[解决办法]
通过JS传递参数！
分别设置菜单的ID， 保存在Url里 然后通过js取得当前url的ID，通过js控制对应菜单展开..

下面是一个自定义用户控件：导航菜单。 你自己建立一个用户自定义控件，然后把下面的代码贴到ascx 文件中就行
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="_menu.ascx.cs" Inherits="admin_usercontrols_menu" %>
<style type="text/css">
#webframe #master-left
{
position: relative;
float: left;
width: 15%;
height: auto;
}
#webframe #master-right
{
position: relative;
float: right;
width: 84%;
height: auto;
}
#accor-nav
{

}
#accor-nav .accor-title

#accor-nav .accor-title a:hover
