Solution 1


First: The valid DateTime string is


Second: Why are you change the DateTime object to string and back to DateTime?

Shouldn't be like this:

DGVCalendar.Rows[row].Cells[0].Value = dt1.ToShortDateString();

hi professional

basically "String was not recognized as a valid date time" error occurs when you did not putting right date time format.

so try this...

DGVCalendar.Rows[row].Cells[0].Value = Convert.ToDateTime(dt1.ToString("dd/MM/yyyy"));

and if it will not work properly then
for more date time formats see below link...[^]

Happy to help
