I just looked at the textField.Mask entry in the language reference…
It says Mask :
[quote]This item has been deprecated since version 2019r2 and should no longer be used.
Please use TextEdit.ValidationMask as a replacement.[/quote]
But when I click on the link for TextEdit.ValidationMask it does not exist in teh docs… Is something that wa planed and abandoned or an inadvertant API 2.0 doc leak?
