I’m trying to show a ComboBox on a PropertyGrid. I don’t mean a dropdown string list because I need the index of the selected item associated with the description.
This is easy to obtain with a ComboBox control on a Form but I can’t get the same result by publishing a ComboBox type property in a PropertyGrid.

On My code below
I’m trying to get a ComboBox on a PropertyGrid.

 public class Wrap {
    private ComboBox _Combo = new ComboBox();
    public Wrap() {

      _Combo.SelectedIndexChanged += new System.EventHandler(Combo_SelectedIndexChanged);

      _Combo.Items.Add(new Item() { Text = "Text1", Value = "Value1" });
      _Combo.Items.Add(new Item() { Text = "Text2", Value = "Value2" });

      _Combo.DisplayMember = "Text";
      _Combo.ValueMember = "Value";
      _Combo.SelectedIndex = 1;
    }

    private void Combo_SelectedIndexChanged(object sender, EventArgs e) {
      ComboBox cb = sender as ComboBox;
      int i = cb.SelectedIndex;
      if (i < 0)
        return;

      Item it = cb.Items[i] as Item;
      string s = it.Value;
    }

    public ComboBox Combo {
      get { return _Combo; }
      set {
        // Temporary test to avoid "null" (the only selection possible from propertygrid)
        if (value == null)
          return;
        _Combo = value;
      }
    }
  }

  public class Item {
    public string Value { set; get; }
    public string Text { set; get; }
  }
