>Sometimes, I have to change my textbox class from my regular textbox class to my disable textbox class. When doing that, I have to drop the class on the form and copy everything from the old textbox to this one an then remove the regular textbox. Is there a faster way?

Why not just use 1 textbox class and add an Enabled_Assign method to your textbox that changes all the properties of the textbox to what the need to be under enabled and disabled conditions.
