</html>后台无代码，不过这得要求你会正确使用Ajax Extensions。网上有很多资料你可以看一下

如果你的树是自己用JS实现的，那么你现在要实现这个当然也就很容易了，如果不是这样的。你可能就需要用
UpdatePanel来实现。

左边的树是结点在第一次加载之后用Session保存起来（用DataTable /Array）。右边加结点时，对Session中保存的内容进行操作，之后加一条刷新左边的JS 脚本
ClientScript.RegisterClientScriptBlock(GetType(), "", "<script>window.parent.frames.左边边框名.location.href = '左边页'; </script>") 左边会对Session 内容重新加载

我没有用ajax.
不用updatepanel能实现吗.

树就是treeview.用js 估计是很难实现左边树刷新的.

右边节点增加完，刷新左边的框架，重新提取数据。
parent.左边框架名.window.location.reload();

reload()我用过了.
问题是: 我左边页面其他节点状态就不能保持了.

用ajax
把你的树的节点写到xml里面去
然后树的状态使用JS控制
在把整个框架的大概设定号
至于点击后局部刷新..使用一个异步传参
把左边树节点做为参数传递给右方,把右面坐为一个单独页面

能说得详细一点吗?还有用js 来增加节点估计做不出来.
出成的代码看不懂.好复杂.生成源码例如:
<table cellpadding="0" cellspacing="0" style="border-width:0;">
<tr>
<td><div style="width:20px;height:1px"></div></td><td><a id="TreeView2n12" href="javascript:TreeView_ToggleNode(TreeView2_Data,12,TreeView2n12,' ',TreeView2n12Nodes)"><img src="/PES.CMS.Web/WebResource.axd?d=i3cF8JjLUc0YN7sa1W4dBIrVplO_6sEf_y0HXesbqQA1&t=633441138476093750" alt="展开演示组织机构" style="border-width:0;" /></a></td><td><a href="OR/OrganiseList.aspx?OrganiseFatherID=16&OrganiseFatherName=%e6%bc%94%e7%a4%ba%e7%bb%84%e7%bb%87%e6%9c%ba%e6%9e%84" target="ContentIframe" onclick="javascript:TreeView_SelectNode(TreeView2_Data, this,'TreeView2t12');" id="TreeView2t12i" tabindex="-1"><img src="../../Images/Manage/tree/bole.PNG" alt="组织机构" style="border-width:0;" /></a></td><td class="TreeView2_1" style="white-space:nowrap;"><a class="TreeView2_0" href="OR/OrganiseList.aspx?OrganiseFatherID=16&OrganiseFatherName=%e6%bc%94%e7%a4%ba%e7%bb%84%e7%bb%87%e6%9c%ba%e6%9e%84" target="ContentIframe" onclick="javascript:TreeView_SelectNode(TreeView2_Data, this,'TreeView2t12');" id="TreeView2t12">演示组织机构</a></td>
</tr>
</table>

感觉用js很难实现.
用ajax 怎么做,有谁给个解决方案!

在操作treeview的时候不需要添加整个树
一开始只递归两层即可
也不要使用iframehtml:
<table style="width: 100%">
    <tr>
       <td valign="top" style="width: 30%">

前面我有说是treeview 啊.

用ajax不就要定时取回发了吗?
那样服务器负担会不会太大了.

呵呵,建议楼主还是用javascript中的ajax来做吧,微软的ajax.net很让你讨厌的

updatepanel难道不用回发吗????而且每次回发都是整页回发,服务器负担更大

现在功能已经出来了.我用的是updatePanel.
如果用javascript中的ajax,我估计我做不出来.
因为要生成这样一段代码:<table cellpadding="0" cellspacing="0" style="border-width:0;">
            <tr>
                <td><div style="width:20px;height:1px"></div></td><td><a id="TreeView2n12" href="javascript:TreeView_ToggleNode(TreeView2_Data,12,TreeView2n12,' ',TreeView2n12Nodes)"><img src="/PES.CMS.Web/WebResource.axd?d=i3cF8JjLUc0YN7sa1W4dBIrVplO_6sEf_y0HXesbqQA1&t=633441138476093750" alt="展开演示组织机构" style="border-width:0;" /></a></td><td><a href="OR/OrganiseList.aspx?OrganiseFatherID=16&OrganiseFatherName=%e6%bc%94%e7%a4%ba%e7%bb%84%e7%bb%87%e6%9c%ba%e6%9e%84" target="ContentIframe" onclick="javascript:TreeView_SelectNode(TreeView2_Data, this,'TreeView2t12');" id="TreeView2t12i" tabindex="-1"><img src="../../Images/Manage/tree/bole.PNG" alt="组织机构" style="border-width:0;" /></a></td><td class="TreeView2_1" style="white-space:nowrap;"><a class="TreeView2_0" href="OR/OrganiseList.aspx?OrganiseFatherID=16&OrganiseFatherName=%e6%bc%94%e7%a4%ba%e7%bb%84%e7%bb%87%e6%9c%ba%e6%9e%84" target="ContentIframe" onclick="javascript:TreeView_SelectNode(TreeView2_Data, this,'TreeView2t12');" id="TreeView2t12">演示组织机构</a></td>
            </tr>
        </table>

呵呵,建议楼主去看看
