これは楽しいものです。
デフォルトの連絡先ビューよりも高速でユーザーフレンドリーな検索を提供し、リードと連絡先を同時に検索できるカスタム検索ページを作成しました。フィルタリングされたビューをクエリするSqlDataSourcesにバインドされたGridViewsを使用します。誰かが私がこれにWebサービスを使用していないと不平を言うと確信していますが、これは私たちが行った設計上の決定にすぎません。
これらのGridViewはUpdatePanelsに存在し、検索時に非常に洗練されたAJAX更新を可能にします。
それはすべてうまく機能しています。1つを除いて、ほぼデプロイの準備ができています。長時間実行される検索の中には、キャッチできないSQLタイムアウト例外がトリガーされているものがあります。

このエラーが発生したときにUpdatePanelsがJavaSriptエラーをスローし始めたため、CRMがこのエラーをキャプチャするためにserver.transferを実行していることがわかりました。IEでJavaScriptデバッガーを使用することによってのみ、完全なエラーメッセージを取得できました。
このエラーを見つけたので、解決策は簡単だと思いました。エラーをキャプチャするには、databind呼び出しをtry/catchブロックでラップする必要がありました。
残念ながら、CRMのIIS構成には、コードに戻る前にこのエラーをキャプチャする魔法の機能があるようです。デバッガーを使用すると、私はそれを見ることはありません。それは私のキャッチブロックに到達することはありませんが、それは明らかに（スタックトレースによって）私のGridViewバインドによってトリガーされているSQLデータソースで発生しています。
これについて何かアイデアはありますか？それは私を夢中にさせています。
