Autocomplete in a Combobox

Hi guys,

today I tried to integrate an autocomplete into my combobox but it does not work. Seems I am forgetting something. Maybe anyone can help me.

I have a collection of items and these items I want to show in a combobox. Additional I want to integrate the autocomplete functionality because the list has 2.000 items.

Here is what I did:

Code:

---

public class ItemInfo
    {
        private string _name = String.Empty;
        private int _id = 0;

        public ItemInfo(int id, string name)
        {
            this.Id = id;
            this.Name = name;
        }
       
        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }

        public int Id
        {
            get { return _id; }
            set { _id = value; }
        }
    }

public class ItemInfoCollection : List<ItemInfo>
    {
        public void Load()
        {
            this.Add(new ItemInfo(1, "A"));
            this.Add(new ItemInfo(2, "AB"));
            this.Add(new ItemInfo(3, "ABC"));
            this.Add(new ItemInfo(4, "B"));
            this.Add(new ItemInfo(5, "BC"));
            this.Add(new ItemInfo(6, "BCD"));
        }
    }


private void Form1_Load(object sender, EventArgs e)
        {
            ItemInfoCollection collection = new ItemInfoCollection();
            collection.Load();

            cbxTestSearch.AutoCompleteMode = AutoCompleteMode.Suggest;
            cbxTestSearch.AutoCompleteSource = AutoCompleteSource.ListItems;

            cbxTestSearch.DropDownStyle = ComboBoxStyle.Simple;
            cbxTestSearch.DataSource = collection;
            cbxTestSearch.DisplayMember = "Name";
            cbxTestSearch.ValueMember = "Id";
        }

---

All seems to work fine. But if I select one entry from the autocomplete list then the autocomplete list close but there is no selected item in the combobox. It is still empty. What do I have forgotten?

Either the CHANGE'd event, or the CLICK'ed event, or any other that react.
MOUSE events as well.
