        listView.SelectionChanging += ListView_SelectionChanging;
        base.OnAttachedTo(bindable);
    }
 
    private void ListView_SelectionChanging(object sender, ItemSelectionChangingEventArgs e)
    {
        if (listView.SelectionMode == Syncfusion.ListView.XForms.SelectionMode.Single)
        {
            if (e.AddedItems.Count > 0)
            {
                var item = e.AddedItems[0] as Contacts;
                item.LabelTextColor = Color.Red;
            }
            if (e.RemovedItems.Count > 0)
            {
                var item = e.RemovedItems[0] as Contacts;
                item.LabelTextColor = Color.Black;
            }
        }
    }
 
    protected override void OnDetachingFrom(SfListView bindable)
    {
        listView.SelectionChanging -= ListView_SelectionChanging;
 
        base.OnDetachingFrom(bindable);
    }
}
