[ASP]动态绑定数据源的GridView添加行 （技术备份）

 GridView 为动态绑定 DataSet，结果 (DataSet)dt = grid1.DataSource 拿不到东西，想偷懒直接添加行不行了， 只好用最笨的办法，把GridView的东西倒成DataSet，然后在DataSet里加行，最后回绑gridview
try里面的
DataTable dtable = new DataTable("tb1");
        
            DataSet ndtset = new DataSet();
           
               for (int i = 0; i < GridView2.HeaderRow.Cells.Count; i++)
            {
             
                dtable.Columns.Add(GridView2.HeaderRow.Cells[i].Text.ToString());
            }
            for (int j = 0; j < GridView2.Rows.Count; j++)
            {
                DataRow ndr = dtable.NewRow();
                for (int c = 0; c < GridView2.Rows[j].Cells.Count; c++)
                {
                    if (GridView2.Rows[j].Cells[c].HasControls())
                    {
