9 Dec 20243 minutes to read

This section briefly explains about how to include ASP.NET MVC Radio Button control in your ASP.NET MVC application using Visual Studio.

Prerequisites

System requirements for ASP.NET MVC controls

Create ASP.NET MVC application with HTML helper

Install ASP.NET MVC package in the application

To add ASP.NET MVC controls in the application, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.EJ2.MVC5 and then install it.

Package Manager
Install-Package Syncfusion.EJ2.MVC5 -Version 28.1.33

NOTE

Syncfusion^® ASP.NET MVC controls are available in nuget.org. Refer to NuGet packages topic to learn more about installing NuGet packages in various OS environments. The Syncfusion.EJ2.MVC5 NuGet package has dependencies, Newtonsoft.Json for JSON serialization and Syncfusion.Licensing for validating Syncfusion^® license key.

Add namespace

Add Syncfusion.EJ2 namespace reference in Web.config under Views folder.

<namespaces>
    <add namespace="Syncfusion.EJ2"/>
</namespaces>

Add stylesheet and script resources

Here, the theme and script is referred using CDN inside the <head> of ~/Pages/Shared/_Layout.cshtml file as follows,

~/_Layout.cshtml
<head>
    ...
    <!-- Syncfusion ASP.NET MVC controls styles -->
    <link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/28.1.33/fluent.css" />
    <!-- Syncfusion ASP.NET MVC controls scripts -->
    <script src="https://cdn.syncfusion.com/ej2/28.1.33/dist/ej2.min.js"></script>
</head>

NOTE

Checkout the Themes topic to learn different ways (CDN, NPM package, and CRG) to refer styles in ASP.NET MVC application, and to have the expected appearance for Syncfusion^® ASP.NET MVC controls. Checkout the Adding Script Reference topic to learn different approaches for adding script references in your ASP.NET MVC application.

Register Syncfusion^® script manager

Also, register the script manager EJS().ScriptManager() at the end of <body> in the ~/Pages/Shared/_Layout.cshtml file as follows.

~/_Layout.cshtml
<body>
...
    <!-- Syncfusion ASP.NET MVC Script Manager -->
    @Html.EJS().ScriptManager()
</body>

Add ASP.NET MVC Radio Button control

Now, add the Syncfusion^® ASP.NET MVC Radio Button control in ~/Views/Home/Index.cshtml page.

CSHTML

@Html.EJS().RadioButton("radio1").Label("Option 1").Name("default").Render()
@Html.EJS().RadioButton("radio2").Label("Option 2").Name("default").Render()

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the app. Then, the Syncfusion^® ASP.NET MVC Radio Button control will be rendered in the default web browser.

Change the Radio Button state

The Radio Button contains 2 states visually, they are as follows:

Checked
Unchecked

The Radio Button Checked property is used to handle the checked and unchecked state. In the checked state an inner circle will be added to the visualization of Radio Button.

CSHTML

@Html.EJS().RadioButton("radio1").Label("Option 1").Name("state").Checked(true).Render()
@Html.EJS().RadioButton("radio2").Label("Option 2").Name("state").Render()
