まず、私がこれまで慣れていたVBA標準から何かをしようとするのは初めてです。ASP.NET（VB）Rowdataboundすべてのデータを整数または小数点ではないテキストとして表示
DBサーバー（SQL Server 10.50.40000）にデータが格納されており、Int/Varchar/decimal (18,2)という名前で保存されています。私はVisual Web Dev 2010を使用してこのデータにアクセスして表示するWebページ（VB）を作成しましたが、何らかの理由でデータにフォーマットすることはできません。e.row.cells(COLUMNNUM).textを介してのみデータにアクセスできますが、試してみるとParse/cast/CInt/TryParseインフォメーションが正しく表示されません。
私は少なくとも20種類の異なるバージョンを試してみましたが、動作するものは何も見つかりませんでした（質問の90％はC＃で、VBの場合は必要ありません）。
