Hi, im looking trying to make a field text[6] with an allowed input format saying 2 letters, a hypen and the 3 letters/numbers.

Example: "DE-AB1"

How do I make the Onvalidate code?

Do I need to make 3 variables:

1. 2 letters

2. The hypen

3. 3 letters/numbers

Or can I make it all in one go?

Have tried some different ways but it wont work.

Thanks in advance.

If you need a simple pattern (adjust as needed)

var

Regex: Codeunit Regex;

Pattern,

Value : Text;

begin

Value := 'AA-AAA';

Pattern := '[A-Z]{2}\-[0-9,A-Z]{3}';

if Regex.IsMatch(Value, Pattern, 0) then

Message('Match')

else

Message('No Match');

end;
