Hi, I was using framework version 4.1 and now I´m starting to learn version 7.1. In 4.1 if I wanted a field to be a "Must Key" I needed to set lMustKey Property. Now I need to use Business Rules. The problem is that in 4.1 when the user left the field empty the Focus was automatically set to the empty filed. Is there any way to have the same behaviour in 7.1?

P.S.: I´m sorry for my English.

Regards,
