Hello Philip, 

we have several applications that showcase our controls and the different scenarios in which they can be used. You can have a look at the Examples/QSF folders within your local Telerik UI for Xamarin installation. Furthermore, in the iOS and Android folders you can examine the native controls. We are constantly working on adding new examples and documentation articles as well as updating the documentation. 

If you need something more specific regarding a control or feature, do not hesitate to ask us so we can point you to the right direction.
