Databinding with ListBox show nothing

 I have a problem when data binding with listbox .

The xaml is : 

    <Grid x:Name="LayoutRoot" Background="White">
        <StackPanel>
            <StackPanel Margin="0,10,0,0">
                <TextBlock Text="MyComponent" FontSize="12" x:Name="txtYourComp" HorizontalAlignment="Center"></TextBlock>
            </StackPanel>
            <ListBox MaxWidth="150" MaxHeight="250"  ItemsSource="{Binding ''}" x:Name="MyDynaComp">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding Path=F_DisplayName}" ></TextBox>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </StackPanel>
    </Grid>

The code file is : 

    public partial class Page : UserControl
    {

        public class MyBaseUserControl : UserControl
        {

            public string F_HolderUsername { get; set; }

            public string F_HolderKey { get; set; }

            public string F_DisplayName { get; set; }
        }

        Dictionary<int, MyBaseUserControl> myAllDynaCompCollection = new Dictionary<int, MyBaseUserControl>();

        public Page()
        {
            InitializeComponent();

            myAllDynaCompCollection.Add(0, new MyBaseUserControl()
            {
               F_DisplayName="MMMMM",
               F_HolderKey="MyKey",
               F_HolderUsername = "MyGod",
            }
            );

            MyDynaComp.DataContext = myAllDynaCompCollection.Values;
        }
    }

These are the whole codes  . 

Why the listbox will show nothing even the cool object really has values ??????????
