It seems that you refer to our components
targeting XamarinForms and more specifically the RadCalendar component. If this is true, you can take a look at our QSF demo application which is currently available for Android and iOS. The name of the application is "Telerik UI for Xamarin Samples" and can be downloaded from both stores.
Also, if you go to your Telerik account you will be able to download our latest release as ZIP archive. It contains a folder named QSF and inside you will find a solution containing the source code of the application and the examples.
I hope this information is helpful.
