ASP.NET MVC database table getting null value - asp.net-mvc

Question

I am creating a simple CRUD application using ASP.NET MVC with Entity Framework, Data are being saved but the values are null when I check it from Database ..
Below I shared different class and files:-
EmployeeController class:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using ASP.NETMVCCRUD.Models;
using System.Data.Entity.Validation;
namespace ASP.NETMVCCRUD.Controllers
{
public class EmployeeController : Controller
{
// GET: Employee
public ActionResult Index()
{
return View();
}
public ActionResult GetData()
{
using (DBModel db = new DBModel())
{
List<Employee> emplist = db.Employees.ToList<Employee>();
return Json(new { data = emplist }, JsonRequestBehavior.AllowGet);
}
}
[HttpGet]
public ActionResult AddOrEdit(int id=0) {
return View(new Employee());
}
[HttpPost]
public ActionResult AddOrEdit(Employee emp)
{
using (DBModel db = new DBModel())
{
db.Employees.Add(emp);
db.SaveChanges();
return Json(new {success = true, message="Saved Successfully",JsonRequestBehavior.AllowGet });
}
}
}
}
AddOrEdit.cshtml
#model ASP.NETMVCCRUD.Models.Employee
#{
Layout = null;
}
#using (Html.BeginForm("AddOrEdit", "Employee", FormMethod.Post, new {onsubmit="return SubmitForm(this)" }))
{
#Html.HiddenFor(Model => Model.EmployeeID)
<div class="form-group">
#Html.HiddenFor(Model => Model.Name, new { #class = "control-label" })
#Html.EditorFor(Model => Model.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(Model => Model.Name)
</div>
<div class="form-group">
#Html.HiddenFor(Model => Model.Position, new { #class = "control-label" })
#Html.EditorFor(Model => Model.Position, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(Model => Model.Position)
</div>
<div class="form-group">
#Html.HiddenFor(Model => Model.Office, new { #class = "control-label" })
#Html.EditorFor(Model => Model.Office, new { htmlAttributes = new { #class = "form-control" } })
</div>
<div class="form-group">
#Html.HiddenFor(Model => Model.Age, new { #class = "control-label" })
#Html.EditorFor(Model => Model.Age, new { htmlAttributes = new { #class = "form-control" } })
</div>
<div class="form-group">
#Html.HiddenFor(Model => Model.Salary, new { #class = "control-label" })
<div class="input-group">
<span class="input-group-addon">$</span>
#Html.EditorFor(Model => Model.Salary, new { htmlAttributes = new { #class = "form-control" } })
</div>
</div>
<div class="form-group">
<input type="submit" value="Submit" class="btn btn-primary"/>
<input type="reset" value="Reset" class="btn " />
</div>
}
Employee.cs
namespace ASP.NETMVCCRUD.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
public partial class Employee
{
public int EmployeeID { get; set; }
public string Name { get; set; }
public string Position { get; set; }
public string Office { get; set; }
public Nullable<int> Age { get; set; }
public Nullable<int> Salary { get; set; }
}
}

Answer 1

Your view contains a #Html.HiddenFor() for each property before the associated EditorFor() method. The DefaultModelBinder only binds the first matching name/value pair and ignores the others, so its the values of the hidden inputs (which are default values) that are being saved.
Remove all the #Html.HiddenFor() from your view and the edited values will be correctly bound.
As a side note, its unclear why your method is named AddOrEdit when all you are doing is adding new records.

Answer 2

[HttpPost]
public ActionResult AddOrEdit(Employee emp)
{
using (DBModel db = new DBModel())
{
db.Employees.Add(emp);
try
{
db.SaveChanges();
}
catch(DbEntityValidationException e)
{
Console.WriteLine(e);
}
return Json(new { success = true, message = "Saved Succesfully" }, JsonRequestBehavior.AllowGet);
}
}
