GridView动态管理行：添加与删除行记录而不影响数据库数据

如果只需删除GridView中的行, 并不删除数据库中的记录

 protected void Button1_Click(object sender, EventArgs e)
        {
            int rowCount = 1;
            DataTable DT = new DataTable();
            DataRow DR;
            DT.Columns.Add("ORDER_NO");
            DT.Columns.Add("EMP_NO");
            DT.Columns.Add("NAME");
            for (int iRow = 0; iRow             {
                 DR = DT.NewRow();
                DR[0] = rowCount;
                DR[1] = GridView1.Rows[iRow].Cells[1].Text.Trim();
                DR[2] = GridView1.Rows[iRow].Cells[2].Text.Trim();
                DT.Rows.Add(DR);
                rowCount++;
            }

             DR = DT.NewRow();
            DR[0] = rowCount;
            DR[1] = this.TextBox1.Text.Trim();
            DR[2] = this.TextBox2.Text.Trim();
            DT.Rows.Add(DR);
            GridView1.DataSource = DT;
            GridView1.DataBind();
            Session["DataTable"] = DT;
        }

        protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
        {
            DataTable DT=(DataTable)  Session["DataTable"];
            DT.Rows.RemoveAt(e.RowIndex);
            GridView1.DataSource = DT;
            GridView1.DataBind();
        }
