    public string Name { get; set; }
}
    public class ViewModel : INotifyPropertyChanged
    {
        private string selectedItems;
        public string SelectedItems

            get
            {
                return selectedItems;

                RaisePropertyChanged("SelectedItems");
            }
        }
        private ObservableCollection<Model> products;
        public ObservableCollection<Model> Products
        {
            get
