现在需要递归加载TreeView value为zuid text为zuname --------------------编程问答-------------------- 以前.net 1.1下用的树形菜单递归算法，你可以参考下。

  /// <summary>
  /// 递归构建节点树
  /// </summary>
  private void CreateNode(string id,TreeNode td)
  {
   Microsoft.Web.UI.WebControls.TreeNode tempNode=null;
   string selectString=null;
   string strNodeText=null;
   string strChildId=null;

   selectString="Menu_Parent=" + id + "";

   DataRow[] dataRows = treeDataSet.Tables["menuTable"].Select(selectString); //搜索当前节点的所有子节点

   foreach(DataRow dr in dataRows)
   {
    tempNode = new Microsoft.Web.UI.WebControls.TreeNode();
    strNodeText = dr["Menu_Name"].ToString();
    strChildId = dr["id"].ToString();
    tempNode.Text = strNodeText;
    td.Nodes.Add(tempNode);   //添加子节点
    CreateNode(strChildId,tempNode);
   }
  }

--------------------编程问答--------------------   public void AddChildNode(DataView dr, TreeNode node,string sql,string yname)
    {
        dr = getview(sql);
        dr.RowFilter = "FatherTreeID = '" + node.Value + "'";//过滤
        foreach (DataRowView drv1 in dr)
        {
            TreeNode ChildNode = new TreeNode();
            ChildNode.Text = drv1["TreeName"].ToString();//
            ChildNode.Value = drv1["TreeID"].ToString();
            ChildNode.Expanded = false;//展开属性为FALSE
            node.ChildNodes.Add(ChildNode);//递归循环插入子节点
            AddChildNode(dr, ChildNode, sql,yname);//递归调用自己
        }
