  14. public ActionResult Index()
  15. {
  16. Employee emp = new Employee();
  17. return View(emp);

  27. }
  28. else
  29. return "You selected department is" + emp.SelectedDepartments;
  31. }
  32. }
  33. }
Create an Employee Class as in Figure 6.

  4. using System.Web;
  6. namespace RadioButtonForApp_MVC.Models
  7. {
  8. public class Employee
  9. {
  10. public string SelectedDepartments { get; set; }
  11. public List<Department> Departments
  12. {
  13. get
  14. {
  15. EmployeeEntities db = new EmployeeEntities();
  16. return db.Departments.ToList();
  17. }
  18. }
  19. }
  20. }
Set up Entity Framework as in Figures 7 and 8.

Index.cshtml

  1. @model RadioButtonForApp_MVC.Models.Employee
  3. @{
  4. ViewBag.Title = "Index";
  5. }
  7. <h2>Index</h2>
  8. @using (Html.BeginForm("Index", "Employee", FormMethod.Post))
  9. {
  10. foreach (var department in Model.Departments)
  11. {
  12. @Html.RadioButtonFor(p => p.SelectedDepartments, department.DepartmentName)@department.DepartmentName
  13. }
  14. <br />
  15. <input type="submit" value="Submit" />
