How do you return the focus to the last used control after clicking a button in a winform app?

Question

I\'m working on a windows forms application (C#) where a user is entering data in a form. At any point while editing the data in the form the user can click one of the butt

Answer 1

Yeah, I admit the requirement is a bit unusual. Some of the information that the users will be entering into this application exists in scans of old documents that are in a couple of different repositories. The buttons facilitate finding and opening these old docs. It's difficult to predict where the users will be on the form when they decide to pull up a document with more information to enter on the form. The intent is to make the UI flow well in spite of these funky circumstances.
