                            SqlDataAdapter adapter = new SqlDataAdapter("SELECT [Artikulli] FROM [Artikujt]", lidhje);
                            adapter.Fill(listaArtikujt);

                            artikulli.DataSource = listaArtikujt;
                            artikulli.DataTextField = "Artikulli";
                            artikulli.DataBind();
                        }
                        catch (Exception ex)
                        {
                            Response.Write("Gabim:" + ex.ToString());
                        }
                    }
                }
            }
    }
}

我想要做的是，在PostBack之后，在我添加了数字2后，它将再次显示2个DropDownlist，2个Textboxes，2个Labels，2个Textbox和2个其他标签。我在Post back后尝试做，在TextBox cmimi = new TextBox();输入一个数字后，它将自动添加到下面的标签中。我想做但没有运气。我希望你理解我的解释。谢谢。：）
