(WPF) Databinding collection to TextBox

Not sure if this is the right forum or not, but to learn data binding I
have 
a window with just 3 controls:
1. Previous Button
2. TextBox
3. Next button

My goal is to bind a collection of names to the TextBox and be able to
cyle 
through them with the two navigation buttons.

Here's the code I have in place for the XAML (WPF)
window------------------------------------

private ListCollectionView view;

public DataNavigator()
{
    InitializeComponent();
    ICollection<string> names = new Data().GetJustNames();
    DataContext = names;
    view = (ListCollectionView) 
CollectionViewSource.GetDefaultView(DataContext);
    view.CurrentChanged += view_CurrentChanged;
}
void view_CurrentChanged(object sender, System.EventArgs e)
{
    btnPrevious.IsEnabled = (view.CurrentPosition > 0);
    btnNext.IsEnabled = (view.CurrentPosition < view.Count-1);
}
private void btnNext_Click(object sender, RoutedEventArgs e)
{
    view.MoveCurrentToNext();
}
private void btnPrevious_Click(object sender, RoutedEventArgs e)
{
    view.MoveCurrentToPrevious();
}
---------------------------------------------------------------------------------------------

Now I'm pretty sure the navigation is working because the buttons become 
disabled correctly.

My only question is how do I set the binding to the TextBox.Text property
in 
XAML?

<TextBox Margin="139,56.5,169,65.5" Name="tbName" Text="{Binding
Path=?}"/>

I'm not sure what the Path should be.
I don't think I have to set the source because the TextBox is within the 
DataContext right?

Thanks for any insight you might be able to provide!
