Before trying to add a custom control, make sure that it is compatible with the .Net version of your current project.

I was trying to add a custom control to toolbox for a project for Windows CE 5.0 and .Net Compact v3.5 on VS2008. I did all those previous suggestions but nothing worked. The control shows up when "show all" is checked but it is grayed , even in "Choose Items" menu is checked.

I created a new project with .Net v2.0 and it worked perfectly.
