You do not need to consider them anymore in programming. They not only do a lot of things, but also stimulate other controls to react. You need to give careful consideration in coding They are passively affected by other controls and provide main showcase for calculation. You need to put data for display They are happy to join others’ calculation by contributing their data. You need to pick data from them for calculation
