Implementing Circular ProgressBars in .NET MAUI

The Syncfusion .NET MAUI Circular ProgressBar (SfCircularProgressBar) displays progress in a circular shape with rich customization options. It supports determinate and indeterminate states, smooth animations, segmented progress, gradient colors, custom angles, and center content. Perfect for task completion, loading indicators, dashboards, and progress tracking.

When to Use This Skill

Use this skill when the user needs to:

• Display circular progress indicators for tasks, downloads, uploads, or operations
• Implement determinate progress with known completion percentages (0-100%)
• Show indeterminate progress when duration is unknown (loading, processing)
• Create segmented progress for multi-step workflows or sequential tasks
• Customize appearance with angles, colors, gradients, thickness, or corner styles
• Add animations with easing effects for smooth progress transitions
• Display custom content at the center (text, icons, buttons, images)
• Handle progress events to respond to value changes or completion
• Build semi-circle or arc progress indicators with custom angles
• Visualize progress ranges with multiple colors for different states

Component Overview

The SfCircularProgressBar control provides:

• Flexible States: Determinate (known progress) and indeterminate (unknown duration)
• Visual Customization: Angles, thickness, colors, gradients, corner styles
• Segmentation: Split progress into multiple segments with configurable gaps
• Animation Support: Smooth transitions with customizable duration and easing
• Range Configuration: Custom min/max values (default 0-100)
• Center Content: Add any MAUI view (text, buttons, images) to the center
• Events: ProgressChanged and ProgressCompleted for interaction
• Rich Gradient Support: Multiple color ranges with solid or gradient transitions
