C# 如何在日历控件天渲染事件asp.net中插入编辑数据

我有下面的代码。当我在特定的日单元格中添加数据时，数据会插入另一个日单元格。请帮助。我的代码中有什么问题。为什么有时数据会正确插入，有时数据会插入另一个日单元格 如： 如果我在23/2中插入日期 插入的数据 19/3

这可能是日期格式的问题。您的hdnSelectedDate.Value是文本，需要采用正确的格式。它的输入是由ShowInfo生成的，您需要确保输入正确，并且该值已转换为有效的日期表示形式。

请使用编辑选项alsoUse convert.ToDate或DateTime.TRIPARSE进行帮助，以便在将HDSELECTEDATE添加到SQL之前将其转换为正确的日期格式。
