Q:
Before I download and test out your product, I was wondering
if your product can do what others can’t? The easiest way for me to
describe what I need it to do is to give you an example.
I have a PDF file with 4 form fields(field1, field2, field3,
field4) and 1 form field (totalField) that is calculated based on what is
entered in the previous 4 fields. Can your software, open and fill in
values into the 4 form fields, then read the calculated value in the
totalField?

A:
Yes, you can use PDFNet API to
implement your requirements. As a starting point I suggest
taking a look at InteractiveForms sample:
This sample shows
both how to retrieve existing and set new values in PDF forms.
In case you are using PDFViewCtrl to fill in existing PDF forms you can setup event handler that will trigger your custom forms logic when the field focus is lost.
