The UI for UWP ListView has a great feature that lets you define a string (or a DataTemplate) that the ListView will show where there are no items in the ItemsSource via the EmptyContent property.
Please add this for the UI for Xamarin RadListView.
Currently RadListView has only pullTorefresh which updates the list if user scrolling the list downwards.. But it is good to have pullUptorefresh kind of gesture. since mostly we need to populate the list when user scrolling up. a gesture direction setting (pullup or down) would do.
