ASP プロジェクトのデータベースにデータ バインドされたリストビュー コントロールがあり、編集できるように設定しています。リストビューはマルチビュー内にあり、情報を完全にロードしますが、編集ボタンをクリックしても何もしません。リストビューは更新パネルにありますが、その一部である可能性がありますが、リストビューを更新パネルの外に置くだけで、マルチビューがビューをデフォルトのページロードビューに戻します。
ほぼ同じ状況で、以前のプロジェクトで完全に機能する編集可能なリストビューを持っていますが、これが機能しない理由がわかりません。削除して再作成しようとしましたが、この問題はマルチビューで作成したリストビューに影響しているようです。「挿入」機能を実装した他のリストビューでは、挿入ボタンも何もしません。
私のコードは以下の通りです：
