title: Controls on WinForm not modifiable in Designer
body: <p>I've inherited a project that has been modified in a way that is beyond me to undo. Every single control on the form is not modifiable in the designer except through the Properties window and each control has an icon in the area below (see image) in the section usually reserved for non-visible items (e.g. DataSource). How do I undo this and return the designer to a usable version without wiping it all out and starting over?</p>
