You can't do it visually. You are left to guess where and how to place additional objects.

Guess you are out of luck.

The other alternative is to design your class visually on a form, then after building, open the hidden files and check the source, then copy and paste into a new class. At least that way you don't have to guess what and where to code the layout, colours etc..

And the product is called Visual Studio and everything is class based - what a joke.
