Silverlight 2.0-将域对象数据绑定到UserControl

我有一个消息类:

public class Message 
{
    public string Text { get; set; } 
    ...
}

我有消息显示Silverlight用户控件,该控件具有消息依赖项属性:

public partial class MessageDisplay : UserControl
{
    public static readonly DependencyProperty MessageProperty =
        DependencyProperty.Register("Message", typeof(Message),
           typeof(MessageDisplay), null);

    public MessageDisplay()
    {
        InitializeComponent();
    }

    public Message Message
    {
        get
        {
            return (Message)this.GetValue(MessageProperty);
        }

        set
        {
            this.SetValue(MessageProperty, value);
            this.DisplayMessage(value);
        }
    }

    private void DisplayMessage(Message message)
    {
        if (message == null)
        {
            this.MessageDisplayText.Text = string.Empty;
        }
        else
        {
            this.MessageDisplayText.Text = message.Text;                
        }
    }
}

}

    <ListBox x:Name="MessagesList" Style="{StaticResource MessagesListBoxStyle}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Silverbox:MessageDisplay Message="{Binding}"></Silverbox:MessageDisplay>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox

我在control.xaml.cs代码中绑定:

    this.MessagesList.SelectedIndex = -1;
    this.MessagesList.ItemsSource = this.messages;

我错过了什么?
