在 C# 中限制“datetimepicker”中的日期

Question

A feature of a forms based application I am developing allows the user to search through a history of records.

The user can search by name, by number, and between dates, and populate the results in a datagridview control.

However, as the form will be used to search for previous records. The ability for the user to select future dates is not required.

Is there a way to prevent the user from selecting future dates, or even grey the future dates out?

Answer 1

You can try with code based on MaxDate property

yourControl.MaxDate = DateTime.Today;

Answer 2

You can use the DateTimePicker.MaxDate Property:

DateTimePicker.MaxDate Property : Gets or sets the maximum date and time that can be selected in the control.

Answer 3

请尝试：

dateTimePicker.MaxDate = DateTime.Now;

Answer 4

Setting the MaxDate property will hide all dates after the specified date, and will not allow dates to be entered that are greater than that date.
