And what exactly was in txtenddate.Text at that time? And what is the locale of the system that runs the code?

Instead of using the Convert class, I'd suggest using DateTime.Parse[^] wrapped in a try..catch block.

While the error may still remain since it's dependent on the input, this would give you more information about the problem.

Also a good practice is to validate the input first. You can use for example TryParse[^] to test if the input is convertible to datetime.
