VisualStudio2012およびSQLServer2012の使用
状況は次のとおりです。
私が構築しているWebサイトは、SQLDataSourceからフィールドにロードされたデータを更新していません。データは適切なテキストボックスに正常に読み込まれますが、データを編集してボタンクリックをアクティブにすると、リビジョンがクリアされ、ページが元の読み込まれたデータに更新されたように見えます。私の知る限り、私のコードは正しいように見えますが、明らかにそうではありません。
追加情報：
マスターページを含むcontainerplaceholderにページを設定しました。
これが私のマークアップです：
