We do not have any documentation for such an approach because it's a general MVVM programming concept and not directly related to a UI for Xamarin control or API. Generally speaking you do no want to directly hook an event into a view model as this breaks the MVVM pattern.
However, there is an approach that you can use that will keep the view decoupled from the view model but still listen for events. You can find many help articles by searching for "Xamarin Forms How to wire up event to view model in MVVM
". A really good post on this topic is from Xamarin themselves, take a look at Turn Events into Commands
(this uses EventToCommandBehavior
Alternatively, you can use the RadListView commands instead of events, you can find more information in the RadListView Commands documentation
