public sealed partial class MainPage : Page
{
    // Custom data item.
    public class ColorOptionDataModel
    {
        public string Label { get; set; }
        public SolidColorBrush ColorBrush { get; set; }

        public override string ToString()
        {

        }
    }

    List<ColorOptionDataModel> colorOptionItems;

    public MainPage1()
    {
        this.InitializeComponent();

        colorOptionItems = new List<ColorOptionDataModel>();
        colorOptionItems.Add(new ColorOptionDataModel()
            { Label = "Red", ColorBrush = new SolidColorBrush(Colors.Red) });
        colorOptionItems.Add(new ColorOptionDataModel()
            { Label = "Green", ColorBrush = new SolidColorBrush(Colors.Green) });
        colorOptionItems.Add(new ColorOptionDataModel()
            { Label = "Blue", ColorBrush = new SolidColorBrush(Colors.Blue) });
    }

    {
        var option = e.AddedItems[0] as ColorOptionDataModel;
        ExampleBorder.Background = option?.ColorBrush;
