How to get next id when click on button next ?

meaning if i have textbox employee id 2 then click next
it must show 3 .

Actually what must i write under BtnNext on view to call Next Function

public class EmployeesController : Controller

    {

        private readonly IEmployees _context;



        public EmployeesController(IEmployees context)

        {

            _context = context;

        }











        // GET: Employees/Create

        public IActionResult Create()

        {

            var model = new Employee();

            model.EmployeeId = _context.GetAll().Max(Employee => Employee.EmployeeId) + 1;









            return View(model);



        }

        public ActionResult Next(int id)

        {

            var nextID = _context.GetAll().OrderBy(i => i.EmployeeId)

                     .SkipWhile(i => i.EmployeeId != id)

                     .Skip(1)

                     .Select(i => i.EmployeeId);





            ViewBag.NextID = nextID;



            return View("Create");

        }



        [HttpPost]

        [ValidateAntiForgeryToken]

        public async Task<IActionResult> Create(Employee employee)

        {

            if (ModelState.IsValid)

            {



                if (employee.EmployeeId <= 0)

                {

                  await  _context.InsertAsync(employee);

                }



                else

                {

                    await _context.UpdateAsync(employee);

                }



                return RedirectToAction("Index");

            }



            return View(employee);



        }





    }

}
