I follow your sample for the Xamarin.Forms listview. But I need to use bahavior to respect the MVVM patturn. So I go my 2 behavior (one for selection and the other for LoadOnDemand)
That work good but when the Listview is created or when I scroll down the LoadOnDemand is called several time. I think is because I do not call
But how I can do that from the viewModel without breaking the MVVM?!
