2.在添加子结点时:
foreach(DataRow oDr in oDs.Tables[0].Rows)
{
    TreeNode tn=new TreeNode(); 
    tn.Text=oDr["Name"].ToString();
    tnStateView.NavigateUrl=oDr["Url"].ToString();//路径
    tv.Nodes.Add(tn);
}

http://218.56.11.178:8009/自己搜搜，开放源码的论坛！里边有TREEVIEW的用法。http://expert.csdn.net/Expert/topic/2248/2248544.xml?temp=.6887018c#的

用Treeview来实现！先下载个Treeview控件然后引入这个控件。下面是这棵树的源码！
//Creat the tree
private void InitTree(TreeNodeCollection Nds,string parentId)
{
DataView dv=new DataView();
TreeNode tmpNd;
dv.Table=mydataset.Tables["MenuClass"];
dv.RowFilter="PID='" + parentId + "'"; foreach(DataRowView drv in dv)
{
tmpNd=new TreeNode();
tmpNd.ID=drv["ID"].ToString();
//set the tooltip
string NodeName;
NodeName=drv["Caption"].ToString();
tmpNd.Text="<span onmousemove=javascript:window.status="+"'"+NodeName+"'"+"; title="+NodeName+">"+NodeName+"</span>"; tmpNd.ImageUrl="../"+drv["Icon"].ToString();
tmpNd.SelectedImageUrl="../image/icon/0001.gif";

tmpNd.Target = "right";
// set the parent,and make it not to link the web
string temp;
temp=drv["Url"].ToString();
if (temp != "0")
{
tmpNd.NavigateUrl="../"+drv["Url"].ToString(); }          
Nds.Add(tmpNd);
//set the parent ID to the next loop
InitTree(tmpNd.Nodes,tmpNd.ID);
}
