How to apply regex mask to New-UDTextBox?

Hi @adam
Sorry for bumping this up but do you habe news on this end?
I was also just trying to get regex to work and indeed it still doesn’t work.

Would like to use this expression for email validation but the textbox doesn’t accept any inputs after setting the mask…

'/^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$/'

Thanks a lot for your help.

Best regards,
Don
