綁定到自定義控件的屬性在代碼中定義的背後

Question

我在後臺代碼中定義的自定義控制：

Public Class MyControl 
    Inherits Button 
    Private _A As String 
    Private _B As String 

    Public Property A() As String 
     Get 
      Return A 
     End Get 
     Set(ByVal value As String) 
      _A = value 
     End Set 
    End Property 
    Public Property B() As String 
     Get 
      Return B 
     End Get 
     Set(ByVal value As String) 
      B = value 
     End Set 
    End Property  
End Class 

而這裏的標記：

<ControlTemplate TargetType="{x:Type local:MyControl}"> 
     <StackPanel> 
     <TextBlock Text="{Binding ?????}"/> <!-- A Property --> 
     <TextBlock Text="{Binding ?????}"/> <!-- B Property --> 
     </StackPanel> 
</ControlTemplate> 

我有什麼代碼寫入到綁定對那些特性？

{Binding Path=A, RelativeSource={RelativeSource AncestorType={x:Type MyControl}}}
