John Simmons gave you a good start, now add the IFormatProvider and the DateTimeStyles to the DateTime.TryParse method, or in the other hand, you can try to add 3 separate boxes, one for day, one more for month and the last one for year

Masked Textbox won't validate date format

Solution 3

First of all, "mm" means minutes, "MM" means months! And now:

DateTime dt;
bool valid = DateTime.TryParseExact(text, "dd/MM/yyyy", null, DateTimeStyles.None, out dt);

This should do the job.

Solution 5

Hi
John is correct. It is your problem don't know how to use Tryparse

See that function accepts a format.

C#

DateTime dob;
DateTimeFormatInfo info = new DateTimeFormatInfo();
info.ShortDatePattern = "dd/MM/yyyy";
DateTime.TryParse("30/3/2011", info, DateTimeStyles.None, out dob);

This way it works. You are ready to search what tryparse doing, instead you are simply looking for ready answer. Better try something.

You could use DateTime.TryParse. If it returns true, the date is valid.
