自动产生树，并建立树结构

    private void Database(TreeView tempTree)
    {
        sqlConn = new SqlConnection(strConn);
        sqlConn.Open();
        SqlDataAdapter adapter = new SqlDataAdapter("select * From PL_Design_Template_TaskItme", sqlConn);
        DataSet ds = new DataSet();
        adapter.Fill(ds);
      
        sqlConn.Close();
        tempTree.Nodes.Clear();
        CreateTreeView(tempTree.Nodes, ds.Tables[0], 0);
    }
    private void CreateTreeView(TreeNodeCollection nodes, DataTable dataSource, int parentId)
    {
        string fifter = String.Format("UpTaskId={0}", parentId);

        DataRow[] drr = dataSource.Select(fifter);
        TreeNode Node;
        foreach (DataRow dr in drr)
        {
            Node = new TreeNode();
            nodes.Add(Node);
            Node.Text = dr["TaskName"].ToString();
            int nodeId = (int)dr["Template_TaskItmeId"];
            Node.SelectAction = TreeNodeSelectAction.None;
            CreateTreeView(Node.ChildNodes, dataSource, nodeId);
            dataSource.Rows.Remove(dr);
        }
    }


自动产生表格，把自动产的树放到表格中

        int numrows;
        int numcells;
        int i = 0;
        int j = 0;
        int row = 0;
        TableRow r;
        TableCell c;
        //产生表格
        numrows = 2;
        numcells = 3;
        for (i = 0; i < numrows; i++)
        {
            r = new TableRow();
            for (j = 0; j < numcells; j++)
            {
                c = new TableCell();
                TreeView tree = new TreeView();
                RadioButton radioBut = new RadioButton();
                radioBut.ID = "radi";
                radioBut.Text = "afdadfasdf";

                tree.ID = "tree" + j.ToString() + i.ToString();

                c.Controls.Add(radioBut);
                c.Controls.Add(tree);

                c.Width = 800;
                Database(tree);
                //c.Controls.Add(new LiteralControl("row" + j + ",cell" + i));
                r.Cells.Add(c);
            }
            Table1.Rows.Add(r);
        }
