谁有05下,asp.net好用的treeview的例子

楼上的例子不错，非常适合初学者，如果不用到数据库，也可以直接在aspx文件里写：<asp:TreeView ID="TreeView1" runat="server" Height="265px" ImageSet="Faq" ShowLines="True" ExpandDepth="1" Target="fmain">
    <ParentNodeStyle Font-Bold="False" />
    <HoverNodeStyle Font-Underline="True" ForeColor="Purple" />
    <SelectedNodeStyle Font-Underline="True" HorizontalPadding="0px" VerticalPadding="0px" />
    <Nodes>
        <asp:TreeNode Text="一级" Value="1" Expanded="true" SelectAction="Expand" >
            <asp:TreeNode Text="二级一" Value="2" NavigateUrl="http://www.baidu.com" Target="fmain"></asp:TreeNode>
            <asp:TreeNode Text="二级二" NavigateUrl="http://www.163.com" Target="fmain"></asp:TreeNode>
        </asp:TreeNode>
    </Nodes>
    <NodeStyle Font-Names="Tahoma" Font-Size="8pt" ForeColor="DarkBlue" HorizontalPadding="5px"
        NodeSpacing="0px" VerticalPadding="0px" />
</asp:TreeView>

<asp:TreeView ID="TreeView1" Runat="server">
  <Nodes>
    <asp:TreeNode Value="Parent1" Expanded="True" Text="1">
      <asp:TreeNode Value="Child1A" Text="A" />
        <asp:TreeNode Value="Child1B" Text="B" />
    </asp:TreeNode>
    <asp:TreeNode Value="Parent2" Text="2">
    </asp:TreeNode>
    <asp:TreeNode Value="Parent3" Expanded="True" Text="3">
      <asp:TreeNode Value="Child3A" Text="A">
      </asp:TreeNode>
    </asp:TreeNode>
  </Nodes>
</asp:TreeView>

上网搜搜，再就是看msdn 或者看看天轰穿的视频教程

就自带TREEVIEW,不过加脚本很麻烦,缺陷

就用vs2005自带的树控件，下面是动态绑定代码：
TreeNode RootNode = new TreeNode();//先添加个根节点
            RootNode.Value = this.TextBox1.Text;
            RootNode.Text = this.TextBox2.Text;
            TreeView1.Nodes.Add(RootNode);
        DataSet ds2 = GridBind(SSHDHAO);//下面开始循环加子节点,你可以嵌套循环来分层
        if (ds2.Tables[0].Rows.Count > 0)
        {
            for (int i = 0; i < ds2.Tables[0].Rows.Count; i++)
            {
                TreeNode Node = new TreeNode();
                string aaa = "";
                Node.Value = ds2.Tables[0].Rows[i]["字段1"].ToString();
                Node.Text = ds2.Tables[0].Rows[i]["字段2"].ToString();
                RootNode.ChildNodes.Add(Node);
            }         }

Index.html文件:
<html>
<frameset cols="150,*">
    <frame name="treeview" src="Default.aspx">
    <frame name="main">
</frameset>
</html>aspx文件:
Default.aspx:
<body>
    <form id="form1" runat="server">
      <div>
        <asp:TreeView ID="TreeView1" runat="server" Target="main">
        </asp:TreeView>
    </div>
    </form>
</body>
Default.aspx.cs文件:
public partial class _Default : System.Web.UI.Page
{
    private OleDbConnection conn;
    private OleDbDataAdapter da;
    private DataSet ds;
    private string sql;    protected void Page_Load(object sender, EventArgs e)
    {
        if ( !this.IsPostBack )
        {
            string connstr = System.Configuration.ConfigurationManager.ConnectionStrings [ "connectionString" ].ConnectionString;
            conn = new OleDbConnection ( connstr );
            sql = "SELECT * FROM [TreeViewTable]";
            da = new OleDbDataAdapter ( sql, conn );
            ds = new DataSet ();
            da.Fill ( ds, "tree" );
            InitTree ( this.TreeView1.Nodes, "000" );
        }
    }    private void InitTree ( TreeNodeCollection nodes, string parentId )
    {
        DataRow [] rows = this.ds.Tables [ "tree" ].Select ( "ParentId='" + parentId + "'" );
        foreach ( DataRow dr in rows )
        {
            TreeNode tmpNode = new TreeNode ();
            tmpNode.Text = dr [ "NodeName" ].ToString ();
            tmpNode.NavigateUrl = dr [ "Url" ].ToString ();
            nodes.Add ( tmpNode );
            string id = dr [ "NodeId" ].ToString ();
            InitTree ( tmpNode.ChildNodes, id );//递归循环添加节点
        }
    }
}
Web.config文件:
<connectionStrings>
    <add name="connectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\data.mdb"/>
</connectionStrings>TreeViewTable表记录如下:
NodeId  ParentId  NodeName  Url
001       000     ...       ...
002       001     ...       ...
003       001     ...       ...
004       002     ...       ...
005       002     ...       ...
006       003     ...       ...
007       003     ...       ...
