PDF Document API for ASP.NET Web Forms - How to implement a PDF viewer

This example demonstrates how to use the Office File API and ASP.NET Web Forms Controls to implement a custom PDF viewer. This PDF viewer displays a PDF document's content as images and allows users to navigate through document pages.

You need an active license for the DevExpress Office File API Subscription or DevExpress Universal Subscription to use the Office File API library in production code.

Overview

Use the following classes to implement the PDF viewer:

• PdfDocumentProcessor
  Allows you to manage PDF files. The PdfDocumentProcessor's LoadDocument method opens a PDF document and the CreateBitmap method converts the document's pages to images.

• ASPxBinaryImage
  Displays a PDF document's pages as images.

• ASPxDataView
  Allows users to navigate through pages.

• ASPxUploadControl
  Allows users to upload a PDF document to the server.

• ASPxCallbackPanel
  Opens a document in the PDF viewer after a user uploads the PDF document to the server.
