Progress Telerik UI for UWP
The RadBusyIndicator control allows you to display an animation which indicates that your application is busy waiting for an asynchronous operation to finish. You can define your own animations and use them with the RadBusyIndicator control.
The control comes with nine predefined animations that can be easily set via the AnimationStyle property.
Besides the out-of-the-box animations, you can create your own animations and integrate them with RadBusyIndicator.
