The flow is : I have a Page A with a listview. This Listiview has ViewCell which has 2 images and some stacklayouts with labels inside. When i click at one item of this Listview, Page B appear, i'm doing some stuff and then i popasync at Page A again. I have to notice that i have a Refresh function inside override void OnAppearing() which Refresh the items of ListView at Page A. This function change the labels and images (By triggers) for each item of ListiView.
