InfoPath Dev

 In an InfoPath 2013 form that uses a custom list, I want to be able to create an edit for a date. This would occur when the user does not use the date picker but uses enters a value. If the user enters a value that is not a valid date, InfoPath will show there is a problem.

However I need to generate a custom error message saying the date is an invalid date format. I know that I can use some kind of a regular expression, but I do not know what regular expression to use. I know the internal storage for the date is different than what is displayed by InfoPath.

Thus can you show me what custom edit pattern I can use to edit a date field?

Hi Jassie,

Are you looking for a custom date pattern? If so then I would recommend using a Validation Rule and use a condition "does not match pattern" to the custom pattern below:

\d\d/\d\d/\d\d\d\d

Please check Jimmy's post here for more information.

Hope this helps.
