To achieve that you need to set the following:
- ProgressValue property of the RadBusyIndicator (value from 1 to 100), whenever you know in your code what progress you have made
- IsIndeterminate property of the RadBusyIndicator - set it to false to enable it to report progress
- BusyContent property of the RadBusyIndicator (optional) - in case you need for instance to write how many percent have passed.
Sample code for how all this can be implemented is just at the same example you have referred:
Just click on View Code
and see the declaration in XAML
You can see how the properties can be set in the BusyIndicatorViewModel.cs
