Logic in the User Interface
In the last chapter, you saw how you can add your own logic to business objects. In this chapter, we will discuss how to implement logic in the user interface layer of the application. The VBCS drag-and-drop features combined with the Quick Starts allow you to build a complete application that can handle query, insert, update, and delete. If that is enough for your needs, you don’t have to read this chapter unless you are curious how VBCS works behind the scenes. But if you want to understand the internals of VBCS and make full use of its power, you need to be able to write your own user interface logic.
