最佳回答

这似乎行之有效:

namespace WindowsFormsApplication2
{
    using System;
    using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            _grid.CellFormatting += new DataGridViewCellFormattingEventHandler( OnGridCellFormatting );

            Column1.DisplayMember = "FullDescription";
            Column1.ValueMember = "ID";
            Column1.Items.Add( new AURecord( "1", "First Item" ) );
            Column1.Items.Add( new AURecord( "2", "Second Item" ) );
        }

        void OnGridCellFormatting( object sender, DataGridViewCellFormattingEventArgs e )
        {
            if ( ( e.ColumnIndex == Column1.Index ) && ( e.RowIndex >= 0 ) && ( null != e.Value ) )
            {
                e.Value = _grid.Rows[ e.RowIndex ].Cells[ e.ColumnIndex ].Value;
            }
        }
    }

    public class AURecord
    {
        public AURecord( string id, string description )
        {
            this.ID = id;
            this.Description = description;
        }
        public string ID { get; private set; }
        public string Description { get; private set; }
        public string FullDescription
        {
            get { return string.Format( "{0} - {1}", this.ID, this.Description ); }
        }
    }
}
