动态生成控件用new的，给你个我写的片段，你参考一下



    /// <summary>

    /// 添加条目

    /// </summary>

    private void AddOneRowForTable()

    {

        //生成一行三列



        TableRow tr = new TableRow();

        TableCell tc = new TableCell();

        TableCell tc2 = new TableCell();

        TableCell tc3 = new TableCell();



        tc.HorizontalAlign = HorizontalAlign.Right;



        tc2.HorizontalAlign = HorizontalAlign.Center;

        TextBox txtTemp = new TextBox();

        txtTemp.Width = 300;

        txtTemp.MaxLength = 30;

        Label lblTemp = new Label();

        lblTemp.Text = "*";

        lblTemp.ForeColor = System.Drawing.Color.Red;

        tc2.Controls.AddAt(0, txtTemp);

        tc2.Controls.AddAt(1, lblTemp);



        tc3.HorizontalAlign = HorizontalAlign.Center;

        LinkButton lbnTemp = new LinkButton();

        LinkButton lbnTemp2 = new LinkButton();

        LinkButton lbnTemp3 = new LinkButton();

        lbnTemp.Text = "删除";

        lbnTemp.Click += lbnDelete_Click;

        lbnTemp2.Text = "上移";

        lbnTemp2.Click += lbnUp_Click;

        lbnTemp3.Text = "下移";

        lbnTemp3.Click += lbnDown_Click;

        tc3.Controls.AddAt(0, lbnTemp);

        tc3.Controls.AddAt(1, lbnTemp2);

        tc3.Controls.AddAt(2, lbnTemp3);



        tr.Cells.Add(tc);

        tr.Cells.Add(tc2);

        tr.Cells.Add(tc3);



        tblItemAdd.Rows.Add(tr);

    }
