I'm trying to use a ListView with RecycleElement. I'm not exactly sure how to handle BindingContext and property change notification using a custom view cell renderer.
Can somebody write sample code for clarification? The following is fuzzy to me:
https://developer.xamarin.com/guides/xamarin-forms/user-interface/listview/performance/
During virtualization the cell will have its binding context updated, and so if an app uses this mode it must handle binding context updates appropriately. All data about the cell must come from the binding context or consistency errors may occur.
If the cells use custom renderers, they must ensure that property change notification is correctly implemented. This is because OnElementChanged events are not raised when cells are recycled. Instead, the cell is retained and its property values change when the binding context is updated to that of an available cell, with OnElementPropertyChanged events then being raised.
