C# Visual Studio WEB SITE で DataList を印刷する方法の調査に 5 日間を費やしました。Web プロジェクトで DataList を印刷できます。サイトにはプロジェクトのような「名前空間」がないため、Microsoft は Web サイトのページを印刷可能にすることを気にしなかったようです。私はかなり大規模な Web サイトをほぼ開発していますが、現在、サイトの主要な機能が使用できないようです。私は助けが必要です！前もって感謝します。
PS マイクロソフトは、プロジェクトとサイトを比較する文献でこの小さな問題について言及していたようですが、そうではありませんでした。
