I guess this is an easy one (but not for beginners like me)...But i can't find the solution. I've created with Tab Box a few tabs. In one of those tabs the user enters some values using numbereditboxes. I would like that if a condition is met, some of my tabs are disabled/hidden or alternatively the numbereditboxes are hiden/disables. How could I do that? Any help much appreciated. Both possibilities interest me. Thanks!
