The GrapeCity.Documents.Pdf.ViewerSupportApi package implements the server-side Support API for the GrapeCity Documents PDF Viewer (GcPdfViewer), and can be used in ASP.​NET Core and Web Forms projects.

  • Real-time collaborative editing mode
  • Annotation and form editors
  • Quick edits using secondary toolbars
  • PDF redaction
  • Signature verification
  • Predefined stamps
  • Other editing features

The full source code of this library together with C# demo projects for ASP.​NET Core and Web Forms is included in the src/ folder in this package. The WEB_FORMS constant is defined for the Web Forms target.
