Getting Started with .NET MAUI RadioButton (SfRadioButton)

This section provides a quick overview for working with the SfRadioButton for .NET MAUI. Walk through the entire process of creating a real world of this control.

Creating an application using the .NET MAUI Radio Button

1. Create a new .NET MAUI application in Visual Studio.
2. Syncfusion .NET MAUI components are available on nuget.org. To add SfRadioButton to your project, open the NuGet package manager in Visual Studio, search for Syncfusion.Maui.Buttons and then install it.

Register the handler

To use this control inside an application, you must register the handler for Syncfusion® core.

using Microsoft.Extensions.Logging;
using Syncfusion.Maui.Core.Hosting;

namespace RadioButtonGettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
                .UseMauiApp<App>()
                .ConfigureSyncfusionCore()
                .ConfigureFonts(fonts =>
                {
                    fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                    fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
                });

#if DEBUG
    		builder.Logging.AddDebug();
#endif

            return builder.Build();
        }
    }
}

Add a basic Radio Button

1. Import the control namespace Syncfusion.Maui.Buttons in XAML or C# code.
2. Initialize SfRadioButton control.

<ContentPage
    . . .    
    xmlns:buttons="clr-namespace:Syncfusion.Maui.Buttons;assembly=Syncfusion.Maui.Buttons">
        <buttons:SfRadioButton x:Name="radioButton"/>     
</ContentPage>

using Syncfusion.Maui.Core;
. . .

    using Syncfusion.Maui.Buttons;
    namespace RadioButtonGettingStarted
    {
        public partial class MainPage : ContentPage
        {
            public MainPage()
            {
                InitializeComponent();           
                SfRadioButton radioButton = new SfRadioButton();
                this.Content=radioButton
            }
        }   
    }

Change the Radio Button state

The two different visual states of the .NET MAUI Radio Button are:

• Checked
• Unchecked

To change the state of the .NET MAUI Radio Button, you can utilize the IsChecked property of SfRadioButton. When the Radio Button is checked, an inner circle is added to its visualization.

You can group multiple Radio Buttons together by using Radio Group. Only one button within a group can be selected at a time.

XAML

    <buttons:SfRadioGroup x:Name="radioGroup">
         <buttons:SfRadioButton x:Name="male" Text="Male"/>
         <buttons:SfRadioButton x:Name="female" Text="Female" IsChecked="True"/>
    </buttons:SfRadioGroup>

C#

    SfRadioGroup radioGroup = new SfRadioGroup();
    SfRadioButton male = new SfRadioButton();
    male.Text = "Male";
    SfRadioButton female = new SfRadioButton();
    female.IsChecked = true;
    female.Text = "Female";
    radioGroup.Children.Add(male);
    radioGroup.Children.Add(female);
    this.Content = radioGroup;

Run the application to render the following output:
