c# 关于重载均与委托不匹配

初学者 不明白这个怎么改求讲解:
e:\VSS\03_开发库\src\RM.Web\RMBase\Test\Web_Form2.aspx(264): error CS0123: “GridView1_RowEditing”的重载均与委托“System.Web.UI.WebControls.GridViewEditEventHandler”不匹配

 protected void GridView1_RowEditing(object sender, GridViewDeleteEventArgs e)

            string name1 = name + ".jpg";

            StorageDBHelp sdb = new StorageDBHelp();
            string sdb_sql = "  select  Picurl from Pricechange_pic where pricechange_id='" + id + "' and picturename = '" + name + "'";

            string url = sdb.check_string(sdb_sql); //.check_account(sdb_sql);

            if (File.Exists(url))
            {

            int result = DataFactory.SqlDataBase().ExecuteBySql(sql);

            if (result > 0)
