I have a numeric field that I want to be formatted as 999-999999-999 so that when users enter 12-digit part numbers, the field automatically formats the value that they have entered. Is there a way to format their value as it is entered so that when they type the fourth number, a hyphen is placed between the third and fourth digit?
Additionally, is there a way to allow a numeric field to have a default value with letters? I want to have a default value of "xxx-xxxxxx-xxx" but I don't want to allow the user to enter anything but numbers in the field. I tried using a text field, but I can't get it to reject letters and only accept numbers.
