Answer 4

RowCommand 下边  我用的是linkbutton   if (e.CommandName == "SmallClass")
        {            try
            {                ClassModel.SD_ClassName = ((TextBox)ClassChild.FooterRow.FindControl("ClassName")).Text;
  if (Bll.Add(ClassModel) > 0)
                {
                    ShowClass();
                }
            }
            catch (Exception ex)
            {
                ClientScript.RegisterStartupScript(GetType(), "Message", "<SCRIPT LANGUAGE='javascript'>alert('" + ex.Message.ToString().Replace("'", "") + "');</script>");
            }
        }
