How to create a Circular Style ProgressBar in Winforms/WPF/ASP.NET

How to create a Circular Style ProgressBar in Winforms/WPF/ASP.NET

Creating a circular-style progress bar in WinForms, WPF, and ASP.NET requires different approaches due to their distinct UI frameworks. Here's how you can achieve it in each technology:

  • Circular Style ProgressBar in WinForms:

In WinForms, you can create a circular progress bar by customizing the appearance of a standard ProgressBar control using the OnPaint method.

Here's an example:

using System; using System.Drawing; using System.Windows.Forms; public class CircularProgressBar : ProgressBar { public CircularProgressBar() { this.DoubleBuffered = true; } protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); e.Graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias; using (Pen pen = new Pen(ForeColor, 3)) { Rectangle rect = ClientRectangle; rect.Inflate(-4, -4); e.Graphics.DrawArc(pen, rect, -90, (int)(360.0 * Value / Maximum)); } } } // Usage in a form: public class MainForm : Form { public MainForm() { CircularProgressBar circularProgressBar = new CircularProgressBar { Size = new Size(100, 100), Location = new Point(50, 50) }; Controls.Add(circularProgressBar); Timer timer = new Timer(); timer.Interval = 50; timer.Tick += (s, e) => { circularProgressBar.Value = (circularProgressBar.Value + 1) % (circularProgressBar.Maximum + 1); }; timer.Start(); } }
  • Circular Style ProgressBar in WPF:

In WPF, you can create a circular progress bar using a Path element and animations.

Here's an example:

<Window x:Class="CircularProgressBarWpf.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="CircularProgressBar" Width="300" Height="300"> <Grid> <Path x:Name="circlePath" Stroke="Green" StrokeThickness="5"> <Path.Data> <PathGeometry> <PathFigure StartPoint="150,5"> <ArcSegment x:Name="arcSegment" SweepDirection="Clockwise" IsLargeArc="False" Point="150,5"/> </PathFigure> </PathGeometry> </Path.Data> <Path.Triggers> <EventTrigger RoutedEvent="Loaded"> <BeginStoryboard> <Storyboard RepeatBehavior="Forever"> <DoubleAnimation Storyboard.TargetName="arcSegment" Storyboard.TargetProperty="Size.Width" From="0" To="150" Duration="0:0:2"/> <DoubleAnimation Storyboard.TargetName="arcSegment" Storyboard.TargetProperty="Size.Height" From="0" To="150" Duration="0:0:2"/> </Storyboard> </BeginStoryboard> </EventTrigger> </Path.Triggers> </Path> </Grid> </Window>
  • Circular Style ProgressBar in ASP.NET:

In ASP.NET, you can create a circular progress bar using HTML, CSS, and JavaScript. You can use a combination of div elements, CSS for styling, and JavaScript or jQuery for animations.

Here's a basic example:

<!DOCTYPE html> <html> <head> <title>Circular ProgressBar</title> <style> .progress-circle { width: 100px; height: 100px; border-radius: 50%; border: 5px solid #ccc; position: relative; overflow: hidden; } .progress-circle .progress { width: 100%; height: 100%; border-radius: 50%; border: 5px solid green; clip: rect(0, 50px, 100px, 0); position: absolute; } </style> </head> <body> <div class="progress-circle"> <div class="progress" id="progress"></div> </div> <script> var progress = document.getElementById("progress"); var degrees = 0; var interval = setInterval(function () { degrees = (degrees + 1) % 360; progress.style.transform = "rotate(" + degrees + "deg)"; }, 20); </script> </body> </html>

These are three different approaches to creating a circular-style progress bar in WinForms, WPF, and ASP.NET. Choose the one that best fits your development environment and requirements.
