{
SfListView ListView;
protected override void OnAttachedTo(ContentPage bindable)
{
ListView = bindable.FindByName<SfListView>("listView");
ListView.SwipeEnded += ListView_SwipeEnded;
base.OnAttachedTo(bindable);
}
private void ListView_SwipeEnded(object sender, SwipeEndedEventArgs e)
{
if (e.SwipeOffset > 100)
ListView.ResetSwipe();
}
}
}
