Installation Wizards
Enhance setup experiences with an attractive progress indicator that shows both current step and overall completion.
Data Processing
Provide visual feedback during lengthy calculations or database operations with configurable text displays showing processed records or remaining time.
Implementation Best Practices
To get the most from the Progress Wheel control:
- Use contrasting colors for progress and background rings to ensure visibility
- Consider adding the InnerShadow effect for a more three-dimensional appearance
- Adjust ring thickness based on your application’s overall design language
- For long-running operations, combine with secondary text to show time remaining
