If there is an existing tab order on a large set of controls on a form, what is the easiest way to insert a control in the middle of that tab order without having to re-number the tab order of all the controls after the one inserted?
Visual Studio has a tool for that. It allows you to click the taborder you want - by selecting the control in the order you want:
the blue boxes(with white numbers) are the current taborder, and white boxes are the new taborder.
