First of all, what do you call "Visual Studio Controls"? If you mean controls you use in the applications or libraries you develop: the answer is simple: there is no such thing. Visual Studio is just the IDE; it does not have those controls.
There is a number of different libraries and project types, each having it's own UI libraries with different and unrelated systems with controls and other UI elements. As you did not bother specify anything, not even platrform(s) and language(s) you wan to use, you will have to find it all by yourself, as other people do anyway, without asking any questions:

Besides, you can set up local Visual Studio help. It is content-sensitive and will show you relevant topics during development. Start with pressing F1.
