I wish add some Custom Controls (that are located in my program) to the Designer Toolbox. I cannot seem to find a way.
As a work around I have created a Custom Control DLL with the controls I want, and it installs them just find.
Ideally I want to be able to make a list of internal controls to add and not have the extra overhead in terms of upkeep and possible code duplication.
Figured out it was a forehead slapper. I simply use typeof for the type and it loads real nice.
var item = new System.Drawing.Design.ToolboxItem( typeof(Controls.ButtonXe.ButtonXe));
