Create More Accessible Forms in PDF Documents Using HTML5


GrapeCity Documents for PDF Viewer (GcPdfViewer), our advanced PDF viewer and editor (Professional Viewer), is included with Documents for PDF and now offers 11 new input types—making it even easier to collect and validate essential data, such as date of birth, telephone numbers, and email.
PDF support for HTML5 includes input types that contain various standard properties. This provides developers with the needed control to ensure consistency through format validation, pick lists, and date picking tools.

Implementation is streamlined since these benefits are already a part of the GcPdfViewer API that developers use in applications like PDF, Excel, and Word.
