Description
ComponentOne PDF supports the creation of Acrobat Forms, documents that contain fields that are filled out by users. Fields are created using the AddField method. Several field types are supported, including text boxes, check boxes, combo boxes, radio buttons, push buttons, list boxes and signatures. This demo requires Adobe Reader to view the PDF.
