Is there a way to use an index value on ComboBox/ListView?

[Ben2146053]

Is there any way to set an index value (like a guid) for each of rows in a listView or combobox but that the index value is hidden from the display?

Yes, is possible. But be aware that you have to always binding the actual selected item to the guid. To display custom data you must implement a class for that and overriding the ToString method. You can add buttons on the right side to Add, Remove and Edit to manipulate items.

	Application.Init ();
	var t = Application.Top;

	List<Product> products = new List<Product> ();
	products.Add (new Product (0, Guid.NewGuid (), "Laptop"));
	products.Add (new Product (0, Guid.NewGuid (), "Desktop"));
	products.Add (new Product (0, Guid.NewGuid (), "Printer"));

	var lv = new ListView (products) {
		Width = Dim.Percent (80),
		Height = Dim.Fill (2)
	};
	var lbl = new Label () {
		Y = Pos.Bottom (lv) + 1,
		Width = Dim.Percent (80),
		Height = 1
	};
	lv.SelectedItemChanged += (e) => {
		lbl.Text = $"{products [e.Item].Key} - {products [e.Item].Name}";
	};
	t.Add (lv, lbl);

	Application.Run ();

	Application.Shutdown ();



class Product {
	public int Index { get; set; }
	public Guid Key { get; set; }
	public string Name { get; set; }

	public Product (int index, Guid guid, string name)
	{
		Index = index;
		Key = guid;
		Name = name;
	}

	public override string ToString ()
	{
		return Name;
	}
}
