DataTable DataC = new DataTable();

private void Page_Load(object sender, System.EventArgs e)
{
//填充数据DataC
CreateNodesOfParent(0,(TreeNode)null);
}

public void CreateNodesOfParent(int iParent,TreeNode pNode)
{
DataView dvwData = new DataView(DataC);
dvwData.RowFilter = "[UpperID] = " + iParent;
TreeView1.AutoSelect = false;
foreach(DataRowView Row in dvwData)
{

if(pNode == null)
{
TreeNode zNode= new TreeNode();
zNode.Text=Row["Name"].ToString();
zNode.ID =Row["ID"].ToString();
zNode.NavigateUrl ="CategoryList.aspx?parent_id="+Row["ID"].ToString()+
"&parent_name="+Row["Name"].ToString();
zNode.Target ="right";
zNode.ImageUrl="../images/folder.gif";
zNode.Expanded=true;
TreeView1.Nodes.Add (zNode);
CreateNodesOfParent(Int32.Parse(Row["ID"].ToString()),zNode);
}
else
{

还好用的，就是首先自己要从网上下载这个控件并安装。
