.csファイルのないスタイルxamlがあります
以下に私のコードの一部を見つけることができます。そこにあなたは見つけることができますTextBlock。ユーザーがアクション（ホバー、クリックなど）を実行したときに、そこでフォントの色を変更したいと思います。ご覧のとおり、のイベントを処理するVisualStateManagerがありますCombobox。Visual State Managerで前景を上書きすることはできますか（たとえば、「クリック」の場合は赤、「ホバー」の場合は青）？
私は自分の問題の解決策を見つけるために多くの時間を費やしましたが、解決策はありません...
誰かが私を助けることができますか？解決策は、私のコントロールからのすべてのスタイルを保持する実装されたxamlファイルにのみあることに注意してください。
