Circular Progress bar in WPF

Ever wanted a slightly different progress bar from the standard WPF Progress bar which looks like the following (IsIndeterminate is like the WinForms Marquee enum value):

C#
1:  <ProgressBar VerticalAlignment="Top"
2:      Height="22" IsIndeterminate="True"/>

What I would like is one that is more like the ones you see all over the web, where we have a round wheel sort of progress indicator. Would you like one of those?

Well fear not, your search is over, here is a very simple idea, just arrange some Ellipses in a circle within a Canvas and do a constant Rotate StoryBoard and bam, a circular progress bar.

Here is the XAML for such a UserControl.

XML
 1:  <UserControl x:Class="Sonic.CircularProgressBar"
 2:      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3:      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4:      Height="120" Width="120" Background="Transparent">
 5:      <Grid x:Name="LayoutRoot" Background="Transparent"
 6:            HorizontalAlignment="Center" VerticalAlignment="Center">
 7:          <Grid.RenderTransform>
 8:              <ScaleTransform x:Name="SpinnerScale"
 9:                              ScaleX="1.0" ScaleY="1.0" />
10:          </Grid.RenderTransform>
11:          <Canvas RenderTransformOrigin="0.5,0.5"
12:                  HorizontalAlignment="Center"
13:                  VerticalAlignment="Center"
14:                  Width="120" Height="120" >
15:              <Ellipse Width="21.835" Height="21.862"

64:                              <DoubleAnimation
65:                                  Storyboard.TargetName
66:                                      ="SpinnerRotate"
67:                                   Storyboard.TargetProperty
68:                                      ="(RotateTransform.Angle)"
69:                                   From="0" To="360"
70:                                   Duration="0:0:01"
71:                                   RepeatBehavior="Forever" />
72:                          </Storyboard>
73:                      </BeginStoryboard>
74:                  </EventTrigger>
75:              </Canvas.Triggers>
76:          </Canvas>
77:      </Grid>
78:  </UserControl>

And here is all the C# codebehind:

C#
 1:  using System;
 2:  using System.Collections.Generic;
 3:  using System.Linq;
 4:  using System.Text;
 5:  using System.Windows;
 6:  using System.Windows.Controls;
 7:  using System.Windows.Data;
 8:  using System.Windows.Documents;
 9:  using System.Windows.Input;
10:  using System.Windows.Media;
11:  using System.Windows.Media.Animation;
12:  using System.Windows.Media.Imaging;
13:  using System.Windows.Navigation;
14:  using System.Windows.Shapes;
15:
16:  namespace Sonic
17:  {
18:      /// <summary>
19:      /// Provides a circular progress bar
20:      /// </summary>
21:      public partial class CircularProgressBar : UserControl
22:      {
23:          public CircularProgressBar()
24:          {
25:              InitializeComponent();
26:
27:              //Use a default Animation Framerate of 20, which uses less CPU time
28:              //than the standard 50 which you get out of the box
29:              Timeline.DesiredFrameRateProperty.OverrideMetadata(
30:                  typeof(Timeline),
31:                      new FrameworkPropertyMetadata { DefaultValue = 20 } );
32:          }
33:      }
34:  }

And here is an example of one of these CircularProgressBar controls in use:

XML
 1:  <Window
 2:      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3:      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4:          xmlns:local="clr-namespace:Sonic"
 5:      x:Class="Sonic.MainWindow">
 6:
 7:
 8:      <Grid>
 9:              <local:CircularProgressBar/>
10:          </Grid>
11:
12:  </Window>

And here it is in action (obviously, it looks better in run time)… Enjoy!

I am using my phone to type this so need to keep it brief. But if you check the prism article from home page of my mvvm framework cinch.codeplex.com there is fully working example in the prism demo app. Look there for async example
