爲什麼保證金不能工作WPF？

Question

<StackPanel Grid.Column="1" Orientation="Horizontal" Margin="0,0,0,0" VerticalAlignment="Top" HorizontalAlignment="Right"> 
    <StackPanel.Resources> 
     <Style TargetType="{x:Type Button}"> 
      <Setter Property="Margin" Value="2,0,0,0"/> 
     </Style> 
    </StackPanel.Resources> 
    <Button Padding="5" x:Name="btnUnlock" Click="btnUserMenu_Click_1" Style="{DynamicResource ButtonStyleBasic}"> 
      <Image Stretch="None" Source="/WpfApplication1;component/Images/view_text.png" ImageFailed="Image_ImageFailed"/> 
    </Button> 
    <Button Padding="5" Margin="2,0,0,0" x:Name="btnUserMenu" Click="btnUserMenu_Click_1" Style="{DynamicResource ButtonStyleBasic}" > 
     <Image Stretch="None" Source="/WpfApplication1;component/Images/personal.png" ImageFailed="Image_ImageFailed"/> 
    </Button> 
    <Button Padding="5" x:Name="btnQuit" Margin="2,0,0,0" Click="btnQuit_Click" Style="{DynamicResource ButtonStyleBasic}"> 
      <Image Stretch="None" Source="/WpfApplication1;component/Images/exit.png" UseLayoutRounding="True"/> 
    </Button> 
    </StackPanel> 

如果我刪除裏面<Button ...保證金無餘量是applied.This是這樣，當我申請自定義模板。這裏是模板...

<Style x:Key="ButtonStyleBasic" TargetType="{x:Type Button}"> 

      <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> 
      <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/> 
      <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/> 
      <Setter Property="BorderThickness" Value="1"/> 
      <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/> 
      <Setter Property="HorizontalContentAlignment" Value="Center"/> 
      <Setter Property="VerticalContentAlignment" Value="Center"/> 
      <Setter Property="Padding" Value="1"/> 

      <Setter Property="Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="{x:Type Button}"> 
        <Border BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" SnapsToDevicePixels="true" CornerRadius="2" BorderThickness="{TemplateBinding BorderThickness}"> 
          <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/> 
        </Border> 
         <ControlTemplate.Triggers> 
          <Trigger Property="IsKeyboardFocused" Value="true"> 

          </Trigger> 
          <Trigger Property="ToggleButton.IsChecked" Value="true"> 

          </Trigger> 
          <Trigger Property="IsEnabled" Value="false"> 
           <Setter Property="Foreground" Value="#ADADAD"/> 
          </Trigger> 
         </ControlTemplate.Triggers> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style>

在樣式的模板不綁定到Margin使用TemplateBinding，因此具有此樣式的Buttons上的保證金屬性將被忽略。
