            {
                return View();


     }
            [HttpPost]
            public ActionResult Register(UserModel um)
            {
                if (ModelState.IsValid)
                {
                    var CurrentUser = (user)Session["loggedInuser"];
                    user u = new user
                    {
                        id = new Guid(),
                        usename = um.Username,
                        password = um.Password,
                        UpdatedBy = CurrentUser.id,
                        UpdateOn = DateTime.UtcNow,
                        CreatedBy = CurrentUser.id,
                        CreatedOn = DateTime.UtcNow,
                        email_id = "abc@xyz.com"

                    };

                    try
                    {
                        db.users.Add(u);
                        db.SaveChanges();
                    }
                    catch (DbEntityValidationException dbex)
                    {
                        throw dbex;
                    }
                    catch (Exception eee)
                    {
                        throw eee;
                    }
                }

                return View();
