Implementing .NET MAUI Range Selector

The Syncfusion SfRangeSelector is a .NET MAUI control that lets users select a numeric range by dragging thumbs over a track. It uniquely supports embedding any content (typically a chart) inside the selector, making it ideal for filtering chart data by range.

When to Use This Skill

Use this skill when the user needs to:

• Set up SfRangeSelector from scratch in a MAUI app
• Embed chart content (SfCartesianChart or other views) inside the range selector for interactive data filtering
• Customize track appearance — colors, height, and extent
• Configure intervals, ticks, labels, and dividers for the range scale
• Style thumb and overlay — size, colors, stroke
• Configure tooltips — show always, styling, custom text
• Implement selection modes — discrete, interval selection, drag behaviors
• Handle events — ValueChanged, ValueChanging, LabelCreated
• Use MVVM commands — DragStartedCommand, DragCompletedCommand
• Customize labels — placement, edge placement, styling, offset
• Style ticks and dividers — colors, sizes, strokes
• Add visual regions — active/inactive region colors and strokes
• Invert range selector direction with IsInversed
• Format displayed labels with prefix/suffix via NumberFormat
• Enable Liquid Glass effect for modern translucent design
• Bind RangeStart/RangeEnd to a ViewModel for MVVM data binding

Component Overview

The SfRangeSelector is a .NET MAUI control for selecting a numeric range by dragging dual thumbs over a track. It uniquely supports embedding any content (typically a chart) inside the selector, making it ideal for interactive data filtering.
