I used advice from this site to set the DoubleBuffering property of a Panel to true.

However, I don't see my new control in my toolbox. To get by I have drawn regular panels in my designer window and then altered the designer file to my new class. This causes headaches though when the designer doesn't open correctly (sometimes it works, other times I get a "variable is undeclared, unassigned error)..

How do I get a simple custom control into my toolbox?
