テンプレート化された親にネストされたコントロールのコンテンツを使用するためにバインドできますか？

Question

System.Windows.Controls.DocumentViewerを使用してFixedDocumentを表示したいTallComponents.PDF.Rasterizerを使用してPDFファイルから作成しました。これは機能していますが、無効にするか、またはDocumentViewerコントロールで表示されるツールバーボタンの一部を削除します。私はテンプレートのexmapleをhereから使用しています。

<Style x:Key="{x:Type DocumentViewer}" 
     TargetType="{x:Type DocumentViewer}"> 
    <Setter Property="Foreground" 
     Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" /> 
    <Setter Property="Background" 
     Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" /> 
    <Setter Property="FocusVisualStyle" 
      Value="{x:Null}" /> 
    <Setter Property="Template"> 
    <Setter.Value> 
     <ControlTemplate TargetType="{x:Type DocumentViewer}"> 
     <Border BorderThickness="{TemplateBinding BorderThickness}" 
       BorderBrush="{TemplateBinding BorderBrush}" 
       Focusable="False"> 
      <Grid KeyboardNavigation.TabNavigation="Local"> 
      <Grid.Background> 
       <SolidColorBrush Color="{DynamicResource ControlLightColor}" /> 
      </Grid.Background> 
      <Grid.RowDefinitions> 
       <RowDefinition Height="Auto" /> 
       <RowDefinition Height="*" /> 
       <RowDefinition Height="Auto" /> 
      </Grid.RowDefinitions> 
      <ToolBar ToolBarTray.IsLocked="True" 
        KeyboardNavigation.TabNavigation="Continue"> 
       <Button Command="NavigationCommands.IncreaseZoom" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         Content="Zoom In" /> 
       <Button Command="NavigationCommands.DecreaseZoom" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         Content="Zoom Out" /> 
       <Separator /> 
       <!-- 
       <Button Command="NavigationCommands.Zoom" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         CommandParameter="100.0" 
         Content="Actual Size" /> 
       --> 
       <Button Command="DocumentViewer.FitToWidthCommand" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         Content="Fit to Width" /> 
       <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         CommandParameter="1" 
         Content="Whole Page" /> 
       <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand" 
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}" 
         CommandParameter="2" 
         Content="Two Pages" /> 
      </ToolBar> 
      <ScrollViewer Grid.Row="1" 
          CanContentScroll="true" 
          HorizontalScrollBarVisibility="Auto" 
          x:Name="PART_ContentHost" 
          IsTabStop="true"> 
       <ScrollViewer.Background> 
       <LinearGradientBrush EndPoint="0.5,1" 
            StartPoint="0.5,0"> 
        <GradientStop Color="{DynamicResource ControlLightColor}" 
           Offset="0" /> 
        <GradientStop Color="{DynamicResource ControlMediumColor}" 
           Offset="1" /> 
       </LinearGradientBrush> 
       </ScrollViewer.Background> 
      </ScrollViewer> 
      <ContentControl Grid.Row="2" 
          x:Name="PART_FindToolBarHost"/> 
      </Grid> 
     </Border> 
     </ControlTemplate> 
    </Setter.Value> 
    </Setter> 
</Style> 

これはリンクされた例と非常によく似ていますが、印刷とコピーのコマンドボタンは削除しました。ユーザーがこれらのボタンを使用できるようにする必要はありません。

私も Zoomコマンドをコメントアウトしなければならなかった

、IDEは、その問題への答えのために、これが有効なコマンドではありませんでしたボーナス票を訴えました。

これはすべてテンプレートを使用した後でもツールバーのボタンにイメージが表示されなくなりました。テキストはContentで指定したものになります。だから私の質問は、 "テンプレートの親にネストされたコントロールのコンテンツを使用するようにバインドできますか？"

Answer 1

Blendを使用してDocumentViewerのテンプレートを抽出して編集したときの結果を以下に示します。あなたが言及している2つのボタンをコメントアウトしました。あなたはSystem.Windows.Documentsの名前空間のインポートが欠けていたので

限りズームコマンドとして、それは無効なコマンドを訴えている場合があります。
