}

我就是加了个 rootnode.Text +="&nbsp<INPUT type='text' value='111'>";//添加文本框

再加100分 http://community.csdn.net/Expert/topic/4912/4912023.xml?temp=.7893793

但是不知道什么原因文本框不支持 Delete键而且文本框得到光标需要点两次

<INPUT type='text' value='111'>改为服务器端组件，Runat=server

对了,你的那个网站的treeview做得很好啊

很喜欢树我写了很多版本的树
看这个ajax版本的树，评价一下下。

这树是假树，和ＭＳ提供的树不一样的，他是ＣＳＳ控制生成的，ajax技术也是这样做树的，里面实现方法这样的 <ul>父
　　　　　　　　　　<li>子
然后ＣＳＳ控制显示，加个textbox,就可以输入值了，再写事件存储到数据库，和平常控件一样写．
