如何使用asp.net 1.1中的webcontrol中的TreeView

第一步
修改web.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>

 <configSections>
        <section name="MicrosoftWebControls" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />   
</configSections>
   
 <MicrosoftWebControls>
 <add key="CommonFiles" value="treepath" />
</MicrosoftWebControls>
   
  <system.web>
...................................
第二步,在想使用此控件的页面加入以下语句
<%@ import namespace="Microsoft.Web.UI.WebControls"%>
<%@ register tagprefix = "iecontrols"
    namespace="Microsoft.Web.UI.WebControls"
    assembly="Microsoft.Web.UI.WebControls"
%>

 <iecontrols:treeview id="tvbasic" autoselect="false" shoplus="true" showlines="true" expandlevel="2"
    runat="server">
    <iecontrols:TreeNode Text="root" Expanded="True">
     <iecontrols:TreeNode Text="Node1" Expanded="True">
      <iecontrols:TreeNode Text="Node11"></iecontrols:TreeNode>
     </iecontrols:TreeNode>
    </iecontrols:TreeNode>
   </iecontrols:treeview>
第三
将控件的这个属性改为空,(转到设计页面右击控件->属性)SystemImagesPath
第四,
在网站中新建一个treepath目录
将C:/Program Files/IE Web Controls/build/Runtime下的文件拷入其中
第五,

写代码
 this.tvbasic.Nodes.Clear();
 TreeNode tn=new TreeNode();
 tn.Text="nodes level1";
 tvbasic.Nodes.Add(tn);
 TreeNode tn2=new TreeNode();
 tn2.Text="level2";
 tvbasic.Nodes.Add(tn2);

 TreeNode tn3=new TreeNode();
 tn3.Text="level3";
 tn.Nodes.Add(tn3);

其它可见
