上面的帖子不算，下面重发    public int SimpleBindTreeView(TreeView TV, int parentID)//DataBoundControl
    {
        return SimpleBindTreeNode(TV, null, parentID);
    }
    public int SimpleBindTreeNode(TreeView TV, TreeNode TN, int ParentID)
    {
        try
        {
            DataTable dt = MyDoSql.GetDt("select Id,ParentID,ItemTextfrom 
CM_MenuItem where  ParentID=" + ParentID + " order by OrderIndex asc,id asc");            if (TV.Nodes.Count == 0)
            {
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    TreeNode oTN = new TreeNode(dt.Rows[i]["ItemText"].ToString(),
 dt.Rows[i]["Id"].ToString());
                    oTN.SelectAction = TreeNodeSelectAction.Expand;
                    TV.Nodes.AddAt(i, oTN);
                    SimpleBindTreeNode(TV, oTN, int.Parse(oTN.Value));
                }
            }
            else
            {
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    TreeNode oTN = new TreeNode(dt.Rows[i]["ItemText"].ToString(), dt.Rows[i]["Id"].ToString());
                    oTN.Target = "mainFrame";
                    oTN.SelectAction = TreeNodeSelectAction.Expand;
                    TN.ChildNodes.AddAt(i, oTN);
                    SimpleBindTreeNode(TV, oTN, int.Parse(oTN.Value));
                }
            }
            return 1;
        }
        catch
        {
            return 0;
        }
    }

Answer 5

  DataTable dt = MyDoSql.GetDt("select Id,ParentID,ItemTextfrom 
CM_MenuItem where  ParentID=" + ParentID + " order by OrderIndex asc,id asc");
每次  都和数据库打交道  没什么效率吧
