他の回答から学んだことに基づいて、これを機能させることができました。他の誰かがそれを必要とする場合に備えて、私はここに解決策を投稿します。
MouseDownイベント中に呼び出すコンポーネントMouseDownManagerを作成しました。押されたばかりのボタンを追跡し、「両方の」ボタンダウンイベントを発生させるために待機しているボタンを判別し、タイマーを開始してそのボタンを待機します。割り当てられた時間内に正しいボタンが押された場合、MouseDownManagerは適切な「両方」のボタンダウンイベントを発生させます。それ以外の場合は、適切なシングルボタンイベントが発生します。フォームでは、MouseDownManagerのMouseDownイベントを処理して、翻訳されたマウスクリックに対してアクションを実行しています。
これで、このコンポーネントをフォーム/コントロールにドロップするだけで、「両方」のクリックに反応できます。
