Implementing SfCircularProgressBar (WPF)
When to Use This Skill
Use this skill when:
- Displaying circular/radial progress for a known task (determinate)
- Showing an indeterminate spinner while progress is unknown
- Visualizing primary + secondary (buffer) progress simultaneously
- Splitting progress into segments (e.g., steps in a workflow)
- Customizing arc angles (semi-circle, full circle, partial arc)
- Styling progress ring colors, gradients, or range-based colors
- Placing custom content (text, buttons, images) at the center of the ring
Assembly: Syncfusion.SfProgressBar.WPF
Namespace: Syncfusion.UI.Xaml.ProgressBar
XAML Schema: http://schemas.syncfusion.com/wpf
Key Class: SfCircularProgressBar
Quick Start
<Window
xmlns:Syncfusion="http://schemas.syncfusion.com/wpf">
<Grid>
<!-- Determinate: shows 70% progress -->
<Syncfusion:SfCircularProgressBar
Progress="70"
ShowProgressValue="True"
Width="150" Height="150" />
</Grid>
</Window>
using Syncfusion.UI.Xaml.ProgressBar;
SfCircularProgressBar circular = new SfCircularProgressBar();
circular.Progress = 70;
circular.ShowProgressValue = true;
circular.Width = 150;
grid.Children.Add(circular);

Common Use Cases
- File upload indicator — determinate with
ShowProgressValue="True" - Loading spinner — indeterminate (
IsIndeterminate="True") - Media player —
ProgressContentwith play/pause button - Step tracker —
SegmentCountmatching total steps - CPU/memory gauge —
RangeColorsmapping green/yellow/red zones - Semi-circle gauge —
StartAngle="180"EndAngle="360"
