You need to evaluate a number of controls to best see what meets your requirements

Is just one example of a controls developed for developers with solid controls

Answer 2

I can also recommend Component One as a good supplier, although I've not tried their PDF document editor, their other third party controls are in my opinion very good. Here are some of the other options I've looked at in the past:

http://www.activepdf.com/products/serverproducts/toolkit/

http://www.aspose.com/docs/display/pdfnet/home

http://itextpdf.com/ (Open Source option which has a reasonable tutorial)

Each have their own benefits and pitfalls so the decision ultimately lies with you comparing each (including cost of course) to determine the best option for you at this time.
