我正在寻找一个 asp.net 控件，它将以网格格式显示全年，每个月为一行，该月中的每一天为列。我发现以下经典的 ASP 脚本可以生成正确的格式：http://www.livio.net/code/calendar_36/CalendarTestYearly36.asp?infomode=HELP（请参阅年历）
是否有类似的东西可用，或者有没有办法在没有特定控件的情况下简单地做到这一点？我是 asp.net 的新手。
谢谢

【讨论】：
您可以使用 ASP.NET 控件的组合来构建它，例如两个转发器，一个用于呈现月份，一个用于呈现日期。这样做是可能的。包括该月的其他日子和包括其中描述的星期几可能会更困难，但绝对有可能。
内部中继器绑定日期，外部中继器绑定月份。
另一种方法可能是动态创建一个 DataTable 类并将所有逻辑用于在表中显示月份。在数据表中将日期创建为列，并为每个月创建一个新行。那也行。
HTH。
