请教如何使用ASP.NET实现树形目录

网络有鬼

用asp.net(vb.net)做导航栏，想把类目录和其子类目录做成象资源管理器那样的树状目录。有什么控件或者方法、或者有这样功能的某个网站的源码吗？ 谢了！

asp.net中有一个控件IE Web Controls，你下载下来然后编译出来就可以用了
The Src folder contains the source code for the IE MultiPage, ToolBar, TreeView, and TabStrip controls, along with related base classes and design-time support.
To build the IE Web Controls:
1.  Make sure you have installed the .NET Framework SDK v1.0 or v1.1
2.  Run Build.bat, which will create a build folder in this directory.   The build folder contains Microsoft.Web.UI.WebControls.dll and a  Runtime directory of supporting files.
To run the IE Web Controls:
1.  Copy the contents of the Runtime directory to the webctrl_client\1_0 directory under your top-level site directory.  For example, if your site root is c:\Inetpub\wwwroot, type this at the command prompt:
xcopy /s /i .\build\Runtime c:\Inetpub\wwwroot\webctrl_client\1_0 /y
    This will create the following directory structure under the site:
      /webctrl_client/1_0
        MultiPage.htc
        TabStrip.htc
        toolbar.htc
        treeview.htc
        webservice.htc
        webserviced.htc
        [images]
        [treeimages]

2.  Create a new web application in IIS and copy the contents of the samples directory to this application directory.  For example:
xcopy /s /i .\samples c:\Inetpub\wwwroot\sampleapp /y
3.  Create a /bin subdirectory for the application and copy the file
Microsoft.Web.UI.WebControls.dll to this directory.

The contents of the application will be as follows:

      /sampleapp
        multipage.aspx
        state_city.xml
        tabstrip.aspx
        toolbar.aspx
        treeview.aspx
        treeview_bound.aspx
        /bin
          Microsoft.Web.UI.WebControls.dll

4.  Request the sample pages from your Internet Explorer web browser, for example: http://localhost/sampleapp/multipage.aspx
