生成的Xaml代碼和自定義C＃代碼不會生成相同的輸出？

Question

我構建了一個xaml類，然後意識到如果我想將它用作抽象基類，它必須在沒有xaml的情況下構建。但是當我完成將xaml轉換爲C＃時，結果不會輸出相同的結果。

E.g.前景不一樣。 （ViewDialogX上左，上ViewDialogC右側）

ViewDialogX.xaml

<ContentControl x:Class="xmlns.ViewDialogX"

      HorizontalAlignment="Center" VerticalAlignment="Center">

     <ControlTemplate TargetType="my:ViewDialogX"> 
      <Border MinWidth="160" MinHeight="90" Margin="1,2,3,3" Padding="4"> 
       <Border.Effect> 
        <DropShadowEffect BlurRadius="10" Opacity="3" ShadowDepth="0" /> 
       </Border.Effect> 
       <GroupBox Header="{TemplateBinding Title}" Background="{DynamicResource ControlBackgroundBrush}">

實現XAML代碼：

<my:ViewDialogX Title="Test"> 
     <Button Content="Button" /> 
    </my:ViewDialogX> 
    <my:ViewDialogC Title="Test"> 
     <Button Content="Button" /> 
    </my:ViewDialogC> 

額外的樣式：

    <Setter Property="BorderThickness" Value="1" /> 
    <Setter Property="Padding" Value="3" /> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="{x:Type GroupBox}"> 
       <DockPanel> 
        <Grid x:Name="HeaderGrid" DockPanel.Dock="Top"> 
         <Border x:Name="BackgroundElement" Background="{DynamicResource NormalBackgroundBrush}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3" /> 
         <Border x:Name="ShineElement" Background="{DynamicResource ShineBrush}" BorderThickness="0" Margin="1" CornerRadius="3" /> 
         <Border x:Name="ShineBorderElement" BorderBrush="{DynamicResource HoverShineBrush}" BorderThickness="1" CornerRadius="2" Margin="{TemplateBinding BorderThickness}" />

        </Grid> 
        <Border DockPanel.Dock="Bottom" Margin="0,-1,0,0" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3"> 
         <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Margin="{TemplateBinding Padding}" /> 
        </Border> 
       </DockPanel>

       </ControlTemplate.Triggers> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 

再次我的問題是：爲什麼不是ViewDialogX和ViewDialogC相同的輸出？

（不知何故ViewDialogC正在編輯組框的前景。）

編輯：

我發現在這條線的前景變化的原因：

group.SetResourceReference(GroupBox.BackgroundProperty, "ControlBackgroundBrush"); 

（請參閱ViewDialogX.xaml我試圖實現）

我可以很難設置背景爲一個特定的c olor或甚至將其綁定到模板父屬性，但是當FrameworkElementFactory獲取動態資源類型的屬性時，則前景將從TemplateParent繼承。這是一個錯誤？

Answer 1

我已經聯繫了Microsoft WPF開發團隊。他們承認這是一個錯誤，但已經將其列爲低優先級並且不太可能被修復。

我的這個例子的工作：使用另一個控件來調用* .SetResourceReference並繪製背景，而不是GroupBox。
