问题
I'm trying to add a radio button to a pdf page I'm rendering through abcpdf. I'm looking at the documentation for abcpdf and it specifies that I use the following code
Doc theDoc = new Doc();
InteractiveForm form = new InteractiveForm (theDoc);
form.AddRadioButtonGroup(new string[2]{"40 610 80 650", "40 660 80 700"}, "RadioGroupField", 0);
The problem is that I don't know what assembly InteractiveForm is referencing so the compiler will error on that line. If I simply add a radiobutton to the html page I'm rendering, it will appear in the pdf but will not be able to be interacted with. Does anyone know what I can use to get InteractiveForm to work, or some other workaround? Thanks in advance.

When you download and install the full .Net package one of the example projects is called Annotations. Within this project is a file called Annotations.cs that has the classes that you're looking for.
