How to create a Progress Ring like Windows 8 Style in WPF?

Question

I want to show progress in my Desktop apps like Windows 8 ProgressRing. This type of progress is shown at times of installation or when Windows Start, but this control can be used in many applications as its very clean and modern, but I don't know how to achieve that. The progress ring image is here.

Please see the image:

May I know how do I code for it may be in XAML or in Code? I have seen that in WPF ProgressRing control is not present, so I have to go to some custom control. Idea link or suggestions please how can I proceed.

Answer 1

Use ProgressRing from MahApps.Metro:

The ProgressRing control is styled after a similar control in Windows 8 to indicate activity rather than a percentage of progress completed.

Example:

<Controls:ProgressRing IsActive="True" />

To change the size of the rings, you need to set Width and Height. Also, you can set a different color for each ring and set the size less than the established. To do this and get this Control without install full MahApps.Metro pack, look at my previous answer:

Make the ProgressRing in MahApps.Metro Smaller

Answer 2

Using MahApps.Metro would be much simpler, but given below is a simple Metro-like wait indicator showing how it would be done in XAML.

It's essentially the same Path object, a filled circle, used 5 times, at 5 different rotation angles and 5 different opacity values for the fill.

Doubtless, there is a more efficient way to do this, but this method shows the animation and timings, as well as the easing to give it more natural, less abrupt feel, when the circles spin around and stop.
