Figure 1: Web application

Choose MVC template as in Figure 2.

Figure 2: MVC template.

Add an Employee Controller as in Figures 3 and 4.

Figure 3: Add Controller.

EmployeeController.cs

  1. using RadioButtonForApp_MVC.Models;
  2. using System;
  3. using System.Collections.Generic;
  4. using System.Linq;
  5. using System.Web;
  6. using System.Web.Mvc;
  8. namespace RadioButtonForApp_MVC.Controllers
  9. {
  10. public class EmployeeController : Controller
  11. {
  12. //
  13. // GET: /Employee/
  14. public ActionResult Index()
  15. {
  16. Employee emp = new Employee();
  17. return View(emp);
  18. }
  21. [HttpPost]
  22. public string Index(Employee emp)
  23. {
  24. if (string.IsNullOrEmpty(emp.SelectedDepartments))
  25. {
  26. return "You did not select any option";
  27. }
  28. else
  29. return "You selected department is" + emp.SelectedDepartments;
  31. }
  32. }
  33. }

Create an Employee Class as in Figures 5 and 6.

Figure 5: Employee Class

Figure 6: Employee Class

Employee.cs

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  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 the Entity Framework as in Figures 7 and 8.

Figure 7: Add ADO.NET Entity Framework

Figure 8: Connection setting

Add the View as in Figures 9 and 10.

Figure 9: Add View

Figure 10: Index View

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. {
  13. @Html.RadioButtonFor(p => p.SelectedDepartments, department.DepartmentName, department.IsSelected == true ? new { Checked = "checked" } : null)@department.DepartmentName
  14. }
  15. <br />
  16. <input type="submit" value="Submit" />
  17. }

The output of the application is as in the following.
