Answer 1

if your CollectionView's ItemsSource is a List<Widget> then each cell will be bound to a single Widget and you can reference the related widget in the event handler. You don't need the index of the row, you can directly reference the bound object

void ValueChanged(object sender, EventArgs args)
{
  var stepper = (Stepper)sender;
  var widget = (Widget)stepper.BindingContext;

  ...
}
