Because the columntype provided by the datagridview does not contain the datetimepicker control. Therefore, it is more difficult to implement columns with input dates. You can add the datetimepicker control to the datagridview by using the following methods.

First, add a datagridview control to the front-end design and name it datagridview1. (Text/piikee)

Then, write the following code to the background. CS file:
