コンボボックスから派生したコントロールを作成しました。アプリケーションのすべてのコンボボックスに共通のスタイルがあります。このスタイルは、私が作成したコントロールを除くすべてのコンボボックスで正常に機能しています。

誰かが私のカスタムコンボボックスに同じスタイルを適用するのを手伝ってもらえますか？

これを試して：

public class FilteredComboBox : ComboBox
{
    static FilteredComboBox()
    {
        DefaultStyleKeyProperty.OverrideMetadata(typeof(FilteredComboBox), 
            new FrameworkPropertyMetadata(typeof(ComboBox)));
    }
}

作成する継承された型ごとに新しい行を作成する必要があるため (おそらく不可能です)、いつでもデフォルトのスタイルを参照できるため、これが気に入らないことを認めなければなりません。

<Style TargetType="{x:Type local:FilteredComboBox}" BasedOn="{StaticResource {x:Type ComboBox}}"/>

C#で毎回ハードコーディングするのと同じだと思います
