Implementing Syncfusion .NET MAUI TimePicker

The Syncfusion .NET MAUI TimePicker (SfTimePicker) is a powerful control that allows users to select time values through an intuitive scrollable interface. It supports multiple time formats, customizable intervals, dialog modes, time restrictions, and extensive styling options.

When to Use This Skill

Use this skill when you need to:

• Implement time selection in .NET MAUI applications
• Add SfTimePicker controls to XAML or C# code
• Configure time formats (12/24 hour, with/without seconds, milliseconds)
• Set up dialog or positioned picker modes
• Define hour/minute/second intervals for time selection
• Restrict selectable times (business hours, appointment slots, blocked times)
• Handle time selection events or use MVVM commands
• Customize picker appearance (header, footer, selection view, text display)
• Implement accessible or localized time pickers
• Troubleshoot TimePicker configuration or behavior issues

Component Overview

The SfTimePicker provides:

• 14 predefined time formats supporting 12/24-hour formats with hours, minutes, seconds, and milliseconds
• Three picker modes: Default (inline), Dialog (popup), and RelativeDialog (positioned popup)
• Time intervals for hours, minutes, seconds, and milliseconds
• Time restrictions including minimum/maximum time and blackout times
• Looping support for seamless navigation between first and last items
• Rich event system with selection changes, dialog lifecycle, and footer button events
• MVVM support through commands (SelectionChangedCommand, AcceptCommand, DeclineCommand)
• Extensive customization for header, footer, column headers, selection view, and text display modes
• Accessibility and localization support for global applications
