When setting a validation on controls on a SmartForm, it will fail with a red border and error:
However, if the borderless setting is set to TRUE on the controls Properties, it will not show a red border or error message on validation.
There are 3 workarounds to consider:
On the validation dialog box, there is an option called “Show validation message in a popup dialog” – this will show a warning message if the validation is not met.
