当我尝试使用dataGridView时，它工作正常，提供日期信息I加载到DGV数据源实际上是一个DateTime值：如果它是一个日期的字符串表示，那么它就无法用它做任何事情。



检查你的数据源：如果它是一个DB，请确保源列是DATE或DATETIME，并且在检索信息时不要使用CONVERT对其进行格式化。

When I try that with a dataGridView, it works fine, provided the date information I have loaded into the DGV data source is actually a DateTime value: if it's a string representation of a date, then it can't do anything with it.

Check your data source: if it's a DB, make sure that the source column is DATE or DATETIME and that you don't format it with a CONVERT when you retrieve the information.
