使いたいです System.Windows.Controls.DocumentViewer
を表示するには FixedDocument
PDFファイルを使用して作成しました TallComponents.PDF.Rasterizer
. 。これは機能していますが、によって表示されるツールバーボタンの一部を無効または削除したい DocumentViewer
コントロール。テンプレートエクスマープルを使用しています ここ.

これはリンクされた例に非常に似ていますが、プリントおよびコピーコマンドボタンを削除しました。ユーザーがこれらのボタンを使用できるようにしたくありません。
私もコメントしなければなりませんでした Zoom
コマンド、IDEは、これが有効なコマンドではなく、その問題に対する答えに対するボーナス投票であると不満を述べました。
これはすべて動作しますが、テンプレートの後、私はもはやツールバーボタンに画像を取得しません。 Content
. 。私の質問は、「テンプレートされた親にネストされたコントロールからコンテンツを使用するためにバインドできますか?」
解決
DocumentViewerのテンプレートを抽出して編集するためにBlendを使用したときに得たものは次のとおりです。あなたが言及する2つのボタンについてコメントしました。
Zoomコマンドに関しては、System.Windows.Documentsの名前空間インポートが欠落しているため、無効なコマンドについて不満を言った可能性があります。
