C # PDF Page action--Set Page toggle button

Overview

In the following example, the method of setting the page toggle button on a PDF document page is described. In the example, the addition of the page toggle button is divided into two cases, one is the settings button to jump to the first page, the next page, the previous page or the last, and the other is the set button to jump to the specified page. The two methods adapt to different programming needs, and can choose the appropriate method of adding.

Description

The code example here needs to use the class library spire.pdf for. NET, version 4.0. When using this class library, you can refer to Spire.Pdf.dll in the project program (DLL files are obtained in the bin file under the installation path).
Such as:

Code operation example (for reference) 1. Jump to a specific page (first, Next, Prev, last)
