Hi,

is it possible to call C# user define function or method when button in a PDF was clicked?

Many thanks in advance

Hi,


The button in PDF file can only call JavaScript code and I am afraid you cannot directly call some C# code when button inside PDF file is pressed. Nevertheless, I will further discuss this requirement with development team and will keep you posted with the required information. We are sorry for this inconvenience.

Hi,


I have further discussed the requirement with development team and I am sorry to share that you cannot call C# code while pressing button inside PDF file. Basically PDF forms can contain JavaScript and XFA forms can also have FormCalc script (see http://www.w3.org/1999/05/XFA/xfa-formcalc-19990614, as per our understanidng, FormCalc is native script language for XML forms).

Your request does not seem to be accomplished and I still wonder why you need to invoke C# code from PDF form?

The fact is that both JavaScript and FormCalc are script languages which serve data in forms. i.e. the kernel of such languages is DOM (PDF fields, annotations etc.) whereas C# is general purpose language and it’s kernel is .NET Platform. Please note that you are not allowed to exceed the limits of PDF document in you script and therefore it’s too hard to support any universal language in the role of script language. Similarly, you can not do anything more with universal language inside PDF form script as compare to performing with simple script language.

As Adobe does not support C# at the moment and we are not entirely certain that if they have any future plans to support this requirement. We are sorry for this inconvenience.
