我相信你可以用下面的办法：

void InitGrid() { 
    gridControl1.DataSource = new List<Person> { 
     new Person(){ ID = 0 }, 
     new Person(){ ID = 1 }, 
     new Person(){ ID = 2 } 
    }; 
    gridView.Columns["ID"].Visible = false; 
    gridView.Columns.Add(new DevExpress.XtraGrid.Columns.GridColumn() 
    { 
     UnboundType = DevExpress.Data.UnboundColumnType.Boolean, 
     Caption = "Mark as Deleted", 
     FieldName = "IsDeleted", 
     Visible = true, 
    }); 
} 
IDictionary<int, object> selectedRows = new Dictionary<int, object>(); 
void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e) { 
    int id = (int)gridView.GetListSourceRowCellValue(e.ListSourceRowIndex, gridView.Columns["ID"]); 
    if(e.IsGetData) 
     e.Value = selectedRows.ContainsKey(id); 
    else { 
     if(!(bool)e.Value) 
      selectedRows.Remove(id); 
     else selectedRows.Add(id, e.Row); 
    } 
} 
void OnDelete(object sender, System.EventArgs e) { 
    //... Here you can iterate thought selectedRows dictionary 
} 
// 
class Person { 
    public int ID { get; set; } 
    public string Name { get; set; } 
    public string Age { get; set; } 
}
