Using a ComboBox as Editor in a Grid

Hi. I am evaluating your products.

I am trying to use a Combox as Editor in the grid. I don’t understand why I can’t use a bindingList as datasource…

 Here is the code of the Form. Any cues would be great. Thanks. See code below.

 private BindingList<PartyType> _listPartyType;
        private BindingList<Personne> _listPersonne;

        public Form1()
        {
            InitializeComponent();
            _listPartyType = new BindingList<PartyType>();
           
            _listPartyType.Add(PartyType.PersonnePartyType());
            _listPartyType.Add(PartyType.CompagniePartyType());

        }

        private void winButton1_Click(object sender, EventArgs e)
        {
            _listPersonne = new BindingList<Personne>();
           
            _listPersonne.Add(Personne.Personne1());
            _listPersonne.Add(Personne.Personne2());
            _listPersonne.Add(Personne.Personne3());
           
            grid.DataSource = _listPersonne;

            ComboBoxEditor multiColumnComboBoxEditor = new ComboBoxEditor(_listPartyType, “DisplayValue”, “ID”, “%DisplayValue%”);
           
            multiColumnComboBoxEditor.TemplateControl.DropDownSize = new Size(250, 150);
            grid.Columns[“PersonnePartyType”].CellEditorManager = multiColumnComboBoxEditor;
            grid.Columns[“PersonnePartyType”].CellViewerManager = new ComboBoxViewer(_listPartyType, “DisplayValue”, “ID”, “%DisplayValue%”);

            //grid.Columns[“PersonnePartyType”].CellEditor.SetWinComboBoxStyle(multiColumnComboBoxEditor.TemplateControl);
            //dataRow.Cells[“Editors”].Value = 4;
        }

This works fine.  The problem is the way you do the binding :

new ComboBoxEditor(_listPartyType, “DisplayValue”, “ID”, “%DisplayValue%”);

should be :

new ComboBoxEditor(_listPartyType, string.Empty, “ID”, “%DisplayValue%”);

The problem is that the ComboBox tries to bind to the “DisplayValue” property on the BindingList<> class, which it does not find.
