I've tried to put this question in the forum but the page keeps disappearing after I click "submit", so here I am...

I have a 3 column GridView and the GridViewComboBoxColumn is not binding correctly.  I've set the following for the grid.

1. DisplayMember = Color
2. ValueMember = Id 
3. DataType =  System.ComponentModel.BindingList`1[TelerikGridViewTests.Models.ColorViewModel]

When I run the application I see "System.ComponentModel.BindingList`1[TelerikGridViewTests.Models.ColorViewModel]" instead of the object within my model.  For my other 2 columns in the grid (a decimal and a string) those are displayed just fine. 

Here is my model code... 

using System.ComponentModel;

namespace TelerikGridViewTests.Models
{
    public class CarsViewModel : ViewModelBase
    {
        public CarsViewModel()
        {
            _cars = new BindingList<CarViewModel>();

            _cars.Add(new CarViewModel()
            {
                Id = 0m,
                Description = "Ford",
                Colors = new ColorsViewModel().Colors,
            });

            _cars.Add(new CarViewModel()
            {
                Id = 1m,
                Description = "Chevy",
                Colors = new ColorsViewModel().Colors,
            });

            _cars.Add(new CarViewModel()
            {
                Id = 2m,
                Description = "Dodge",
                Colors = new ColorsViewModel().Colors,
            });
        }

        BindingList<CarViewModel> _cars;
        public BindingList<CarViewModel> Cars { get { return _cars; } set { _cars = value; } }
    }

    public class CarViewModel : ViewModelBase
    {
        public decimal Id { get; set; }
        public string Description { get; set; }

        BindingList<ColorViewModel> _colors;
        public BindingList<ColorViewModel> Colors
        {
            get { return _colors; }
            set { _colors = value; }
        }
    }

    public class ColorsViewModel : ViewModelBase
    {
        public ColorsViewModel()
        {
            Colors = new BindingList<ColorViewModel>();

            Colors.Add(new ColorViewModel()
            {
                Id = 1,
                Color = "Blue",
            });
            Colors.Add(new ColorViewModel()
            {
                Id = 2,
                Color = "Red",
            });
            Colors.Add(new ColorViewModel()
            {
                Id = 3,
                Color = "Green",
            });
            Colors.Add(new ColorViewModel()
            {
                Id = 4,
                Color = "Yellow",
            });
        }

        public BindingList<ColorViewModel> Colors { get; set; }
    }

    public class ColorViewModel : ViewModelBase
    {
        public int Id { get; set; }
        public string Color { get; set; }
    }
}

and code which binds the model..

using System.ComponentModel;
using System.Windows.Forms;
using TelerikGridViewTests.Models;

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

            BindingList<CarViewModel> _cars = new CarsViewModel().Cars;
            radGridView1.DataSource = _cars;
        }
    }
}
