Public Property Text As String
    Get
        Return GetValue(TextProperty)
    End Get
    Set(ByVal value As String)
        SetValue(TextProperty, value)
    End Set
End Property
Private Sub TextPropertyChanged()
    If String.IsNullOrEmpty(Text) Then
        TextBox1.Text = ""
    Else
        TextBox1.Text = Text
    End If
End Sub
Private Sub TextBox1_LostFocus(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles TextBox1.LostFocus
    Text = TextBox1.Text
End Sub

I can bind in both XAML and code behind.
