cultureInfo calendar DateTime problem

[Guest]

Hi all,

In a user control, the user can put the cultureinfo to his preference,
choosing between "nl-BE","fr-BE", and "en-US". this way all calendar and
datetime properties are set in the right structure.
In a webform I have two textboxes which are filled in by a CalendarPicker in
a Pop-up window, a StartDate and an EndDate.

Works fine.

But on Form.submit, the two textbox.Text are converted by this method
DateTime.ParseExact(TextBox.text, 'ddd,dd MMM yyyy', format)
where format is CurrentCulture.CultureInfo

This works fine if the user does not change his language preferences (and
thus the cultureInfo).

But he wants his application to work in english or french, he gets a
'Datetime is not valid' parser error

Anyone ?

You're getting the error because ParseExact is trying to deal with a
hardcoded date format that make no sense for some cultures. Imagine what
happens when the user enters 15 for the day but it is being used in the code
as the month value.

The whole page and its controls need to use the same culture info, including
the UI culture.

You might want to try it without ParseExact to see if the datetime will be
accepted for the selected culture.

the user cannot manually add the date to the textbox, it goes with a pop-up
window, a calendar tool and the value is formatted to the same string as the
one parseExact uses
