I would like to create/validate input mask for "Email" field for customer card(Customer Card-form>Communication-Tab>Email).
ie. when user Copy and paste any mail to "Email field" ,and if that contain commas, carriage returns or tabs; Its should show error(remove commas, carriage returns or tabs).
I tried this code in customer card, Email(field): OnValidate() trigger:
[Var - Ch(Text)]
Ch := 9; //for tab
Ch := 13; //for carriage return
Ch := 10; //for line feed
Ch := ',';
IF(Customer."E-Mail" = Ch) THEN
But its not triggering.
Even , I tried the same code for same field for customer table, but its not triggering.
Please advice me , what I am doing wrong or Advice me the alternate way to do.
