This topic includes step-by-step instructions to add button component to PDF using C# programming language, as well as sample code example for the insertion of button in PDF. To insert button in PDF using C#, we will use one of the most well-liked annotation library and develop a sample code example. In addition, we will explain how to configure the annotation package. Here are detailed instructions for adding a button component to a PDF document using C#.

Steps to Add Button Component to PDF using C#

1. Install GroupDocs.Annotation for .NET package from the NuGet to insert button in PDF
2. Add reference to the GroupDocs.Annotation namespace
3. Instantiate Annotator object by passing path of input PDF to it
4. Instantiate ButtonComponent object with some properties like position, page number, etc.
5. Call Annotator.Add method and pass ButtonComponent object to it
6. Call Annotator.Save method with resultant PDF path

Using the above vital steps, you can easily create button component in PDF using C# with few API calls of annotation library. You just need to load PDF in Annotator class, add ButtonComponent to Annotator and finally save the PDF to disk. No additional software is required to use the annotation library on Windows, macOS, and Linux operating systems. Here is the sample C# code example to insert customize button in PDF document.

Code to Add Button Component to PDF using C#

In above section, we illustrated how to add button in PDF using C#, set up the annotation package, and how to generate a colourful button in a PDF document using a few calls of annotation library’s API. You can also use it to insert checkbox and dropdown components in PDF. You can set the position, color, border style and other properties of button using ButtonComponent.

We have discussed the complete process for developing an application to insert button component in PDF and wrote sample code for it. An article we published recently about adding link annotation to PDF, have a look at how to add link annotation to PDF using C# guide for more information.
