Question

How to add functionality to buttons( Next previous first last) navigation buttons to primary key field using mvc

==========Problem==========

Cannot add functions to Next previous last first for create action using repository pattern based on EmployeeId field

==========Example==========

Employee Id : 5 as last record

IF create action view get loaded it must show max+1 for Employee Id meaning it will show 6

IF Click NextButton become 6

IF Click previousButton become 4 and get another data related as name age,etc...

IF Click LastButton become 5 and get another data related as name age,etc...

IF Click FirstButton become 1 and get another data related as name age,etc...

==========Details Code===========

I work in employee controller in action create

View action create have 4 buttons (First - Last - Next - Previous)

when create action loaded it will come with max number + 1 for EmployeeId

and after that using button previous next last first )

===========Employee Controller Have Create Action=====

public class EmployeesController : Controller
{
private readonly IEmployees _context;

public EmployeesController(IEmployees context)
{
_context = context;
}

// GET: Employees
public async Task<IActionResult> Index()
{
return View(await _context.GetAllAsyn());
}

// GET: Employees/Create
public IActionResult Create()
{
How to call functions below
// var maxId = maxid+1;
getNext()
getprevious()
getlast()
getfirst()
return View();
}
===============Generic Repository Pattern(required function I dont know======
public class EFRepository<T> : IRepository<T> where T : class
{
protected TabDbContext _context { get; set; }
public EFRepository(TabDbContext context)
{
_context = context;
}
getNext(){
what implementation write
}
getprevious()
{
what implementation write
}
getlast()
{
what implementation write
}
getfirst()
{
what implementation write
}
public IQueryable<T> GetAll()
{
return _context.Set<T>();
}

public virtual async Task<ICollection<T>> GetAllAsyn()
{

return await _context.Set<T>().ToListAsync();
}

public virtual T Get(int id)
{
return _context.Set<T>().Find(id);
}

public virtual async Task<T> GetAsync(int id)
{
return await _context.Set<T>().FindAsync(id);
}

public virtual T Find(Expression<Func<T, bool>> match)
{
return _context.Set<T>().SingleOrDefault(match);
}

public virtual async Task<T> FindAsync(Expression<Func<T, bool>> match)
{
return await _context.Set<T>().SingleOrDefaultAsync(match);
}

public ICollection<T> FindAll(Expression<Func<T, bool>> match)
{
return _context.Set<T>().Where(match).ToList();
}

public async Task<ICollection<T>> FindAllAsync(Expression<Func<T, bool>> match)
{
return await _context.Set<T>().Where(match).ToListAsync();
}

}
