how to restrict only letter fields in input field in outsystem

  
I want only letter input to be entered in input field.

when a user enters special character or numbers ,

and click on submit button

the input must not enter the special character ,

and do not save it to database.


is there any way to achieve this??

If you search the Forge for 'mask' you will find four different components that do masks of various types.  You'll have to experiment to see which works best for you but the one called Majora is the one I would start with.

Hope this helps,
