Use the OnAppaering() method inside a ContentView

Question

I am trying to implement a TabView. As the content of each Item I inserted pages that I had previously created, transforming them from ContentPage to ContentView. By doing this, however, it is no longer possible to use the override of the OnAppaering() and OnBackButtonPressed() methods. Is there a way to use these two methods within the ContentView?

Hello,​

Welcome to our Microsoft Q&A platform!

The ContentView doesn't have the lifecycle events. Did you use Xamarin.Community.Toolkit.TabView to display the views? To detect the lifecycle events, try using contentPages instead and using Shell to for the template.

Here is a similar issue case that may help you.
