Working with RadioButton and DropDownList in ASP.NET MVC

A RadioButton and DropDownList plays a vital role in any project development and provide very essential function to work on. Hence here I am explaining how can we use radio buttons and dropdown list in ASP.NET MVC application.

Steps to use RadioButton and DropDownList

Step 1: Open Visual Studio 2010 and chose new>project



Step 2: Now select an empty asp.net mvc web application>Give name to the application and click on add.



Step 3: Now firstly route the path in global.asax.cs by manipulating the code as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

namespace Useofradiobypacific
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,
// visit http://go.microsoft.com/?LinkId=9394801
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "PC", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
}
}

Step 4: Now add a new controller by following these steps:

1. Right click on the controller folder in solution explorer.
2. Chose add>controller and name the controller as show.

Step 5: Code the controller as per user requirement as in this example we want to use a radio button to chose the favorite technology and for the different employee of an organization:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace Useofradiobypacific.Controllers
{
[HandleError]
public class PCController : Controller
{
public ActionResult Index()
{
ViewData["Message"] = "Welcome to MCN SOLUTION PVT LTD";
List<string> NameList = new List<string>();
NameList.Add("Prashant");
NameList.Add("Akash");
NameList.Add("Arjun");
NameList.Add("Darwin");
ViewData["name"] = new SelectList(NameList);
return View();
}
public ActionResult HandleForm(string name, string preferredtechnology)
{
ViewData["name"] = name;
ViewData["preferredtechnology"] = preferredtechnology;
return View("FormResults");
}
}
}
