データベースにテーブルtblexpenseがあります。Taxinreal、Taxinpercent、* Amount * NetAmountという名前の列があります。* NetAmount * は * (Amount-Taxinreal-Taxinpercent) に等しい計算列です* 今、私が欲しいのは実行時に aspx ページでユーザーが挿入できる必要があることですamount,tax,taxinpercentageおよびユーザーNetAmountによって提供された値に応じて実行時に計算（Netamount = Amount-Tax-Taxpercentage）し、データベースに挿入する必要があります。この目的のために、必要な数学的操作を実行する差分ボタンがあります。私が抱えている問題は、リストビューを使用していることです。新しいボタンを追加するのは簡単ですが、差分ボタンのクリックイベントで必要な数学的操作を実行するにはどうすればよいですかデータベースで更新されました??? 早急に解決策が必要です (PS Listview のみを使用する必要があります)。
