        public ActionResult Edit(int? id)
        {

            var member = repository.GetMember(id, _context);

            return View(member);

        }




        [HttpPost]
        public ActionResult Edit(Member member)
        {



            _context.Entry(member).State = EntityState.Modified;

            _context.SaveChanges(); //geting  error 

            TempData["edit"] = "member succesfully edited";
