Adding Radio Button Control in Web API

Introduction

In this article, I will show you how to add a RadioButton control in the Web API. We use the radio button in a group in which we select only one at a time. When the user uses the radio button then the user makes a choice among a set of absolute and related options. The user can select only one option from the radio buttons set. Radio Buttons are so called because they work like channels on a radio.

Now see an example of adding the radio button control in the Web API.

Step 1

Create a Web API application as in the following:

Start Visual Studio 2012.
From the start window select "Installed" -> "Visual C#" -> "Web".
Select "ASP.NET MVC4 Web Application" and click the "OK" button.
From the "MVC4 project" window select "Web API".
Click the "OK" button.

Step 2

Select the "HomeController.cs" file and write some code. This file exists in:

In the "SolutionExplorer".
Select "Controller" -> "HomeController".

Add the following code in this file:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace RadioAPI.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public string Display(FormCollection form)
{
string selectlanguage = form["language"];
return "Selected Language: <b>" + selectlanguage + "</b>";
}
}
}

Step 3

Add a View page "MVC 4 View Page (ASPX)" named "Index.aspx".

In the "Solution Explorer".
Right Click on the "Home" -> "Add" -> "New Item".
Select "Installed" -> "Visual C#" -> "Web" -> "MVC 4 View Page(ASPX)".
Click the "Add" button.

Add the following code in this view page:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
<html>
<head id="Head1" runat="server">
<title>Index</title>
</head>
<body>
<% using (Html.BeginForm("Display","Home",FormMethod.Post)) { %>
<div><b>Choose any Language: </b><br />
<br /> <%= Html.RadioButton("language", "C#") %> C#
<br /><%= Html.RadioButton("language", "C++") %> C++
<br /><%= Html.RadioButton("language", "C") %> C
<br /> <%= Html.RadioButton("language", "Java") %> Java
<br /> <%= Html.RadioButton("language", "HTML") %> HTML
<br /> <%= Html.RadioButton("language", "Javascript") %> Javascript
<br /><br />
<input type="submit" value="Submit" />
</div>
<%} %>
</body>
</html>

Step 4

Execute the application by pressing "F5". The output will be shown like this:

Select any language and click on the submit button.
