Basically, there are 2 places you can do it: in the Class designer or in a program. Some classes (like classed derived from Column, Header, etc) can be defined only in a prg. I prefer the class designer. Many other people will argue that it's easier in a prg. I believe it depends mostly on being a good typist or a good clicker. Also, on how well you can remember the names of methods, properties, parameters. I prefer to chose them form lists (as in class designer)...
