Implementing .NET MAUI Radio Buttons

Guide for implementing Syncfusion .NET MAUI Radio Button (SfRadioButton) - a selection control that allows users to select one option from a set with checked and unchecked states.

When to Use This Skill

Use this skill when you need to:

• Implement radio buttons for mutually exclusive selections in .NET MAUI
• Create grouped radio button sets where only one option can be selected
• Handle radio button state changes and user interactions
• Customize radio button appearance (colors, sizing, text styling)
• Implement GroupKey-based or SfRadioGroup-based grouping
• Work with radio button events (StateChanged, StateChanging)
• Apply VisualStateManager to radio buttons
• Create forms with single-selection options (payment methods, preferences, etc.)

Component Overview

The Syncfusion .NET MAUI Radio Button (SfRadioButton) provides:

• Two States: Checked and unchecked with visual feedback
• Grouping: Multiple approaches (SfRadioGroup, GroupKey) for mutual exclusion
• Events: StateChanged and StateChanging for interaction handling
• Customization: Extensive styling options for colors, text, sizing
• Visual States: VisualStateManager integration for advanced styling

Grouping and Organization

📄 Read: references/grouping.md

• GroupKey approach: Group radio buttons across different layouts
• CheckedItem property: Retrieve the currently selected radio button
• SfRadioGroup container: Automatic mutual exclusion management

• Choosing between GroupKey and SfRadioGroup approaches
• Multiple independent groups in the same view
• Advanced grouping scenarios and patterns

Events and Interaction

📄 Read: references/events.md

• StateChanged event: Detect when radio button state changes
• StateChangedEventArgs: Access new state information
• StateChanging event: Intercept and cancel state changes
