Implementing .NET MAUI Date Time Range Slider

This skill provides comprehensive guidance for implementing the Syncfusion .NET MAUI DateTime Range Slider (SfDateTimeRangeSlider) control, a highly interactive UI component that enables users to select a range of DateTime values with dual thumbs.

When to Use This Skill

Use this skill when the user needs to:

• Implement a range slider for selecting DateTime ranges in .NET MAUI apps
• Create date range pickers with visual track, thumbs, and labels
• Build time range selectors with hour/minute/second granularity
• Add dual-thumb sliders for min-max date/time selection
• Implement interactive calendars with range selection via slider
• Customize track, thumb, tick, label, divider, or tooltip appearance
• Configure discrete stepping through DateTime values
• Handle value change events or implement MVVM commands
• Apply the modern Liquid Glass Effect on iOS 26+/macOS 26+ platforms
• Support horizontal and vertical orientations with RTL
• Style active/inactive regions separately for selected ranges

This skill covers the complete API surface including installation, configuration, styling, events, commands, and advanced features like deferred updates and interval selection.
