>I have a custom base textbox. I put it on a winform and then I modified properties and added some code to events. I want to take this control from the form and make a separate new base textbox. Is there any easy way to do that?

In VFP this would be very easy :)

I'm curious how to do this in .NET.

Can you take the code from Form's Designer and move it to a class? Though may be there is a visual way.
