Q: I am looking for PDF Viewer and Form field data extractor control
to achieve following:
1. PDF with AcroForm should be able to load in Viewer control.
2. User should be able to edit the form fields.
3. To be able to retrieve the form field values as well fill
programmatically.
Please let me know if this can be achieved with PDFNet SDK?

A: As a starting point you may want to take a look at PDFViewSimple
and PDFView sample projects:
PDFViewSimple: http://www.pdftron.com/pdfnet/samplecode.html#PDFViewSimple
PDFView: http://www.pdftron.com/pdfnet/samplecode.html#PDFView
For an example of how to programmatically manipulate (fill-in or
extract) PDF forms, please take a look at InteractiveForms and FDF
samples:
InteractiveForms: http://www.pdftron.com/pdfnet/samplecode.html#InteractiveForms
FDF: http://www.pdftron.com/pdfnet/samplecode.html#FDF
All of the samples are included as part of PDFNet SDK (http://
www.pdftron.com/pdfnet/downloads.html).
In case you will be manipulating a form that is opened in PDFViewCtrl
please make sure that you lock the document while manipulating the
document. For example:
view.GetDoc().Lock();
… read/write form fields
view.GetDoc().Unlock();
