Alignment vs ContentAlignment   

Consider a Window W, Button B, and TextBlock T where

W.Content = B
and 
B.Content = T


T may be aligned inside B by setting B.HorizontalContentAlignment and
B.VerticalContentAlignment. However T.HorizontalAlignment and
T.VerticalAlignment have no effect.

B may be aligned inside W by setting B.HorizontalAlignment and
B.VerticalAlignment. W.HorizontalContentAlignment and
W.VerticalContentAlignment have no effect.


Is there a rule that may be deployed to determine whether these
properties should be set on the parent (using
HorizontalContentAlignment and VerticalContentAlignment) or on the
child (using HorizontalAlignment and VerticalAlignment)? It seems a bit
unfair to have to guess. The documentation is not very helpful in this
regard.


{example code follows }

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;

namespace AlignmentQuestions {
  class MainWindow : Window {

    [STAThread]
    public static void Main() {
      new Application().Run(new MainWindow());
    }

    public MainWindow() {
      Width = 2 * 96; Height = 2 * 96;
      Button button = new Button();
      TextBlock text_block = new TextBlock(new Run("Button"));
      button.Content = text_block;
      this.Content = button;

      //align text in button  
      //works
      button.VerticalContentAlignment = VerticalAlignment.Top;

      //does not work
      //text_block.VerticalAlignment = VerticalAlignment.Top;
      

      //align button in window
      //does not work
      //HorizontalContentAlignment = HorizontalAlignment.Left;

      //works
      button.HorizontalAlignment = HorizontalAlignment.Left;
    }
  }
}
