After reviewed about few products of report generation, we selected syncfusion DocIO for our developments. I glad to say that we have chosen correct product. This is really helpful us for rapid application development. I have used most of the features in DocIO and few features in PDF. I used libraries to automated mail generating module which has variety of functions like mail merge, doc to pdf, encrypt documents, sign documents, doc to html ,etc…and we are intend to use syncfusion for our upcoming projects. It’s not difficult to deal with their libraries and if we get problem we’ll get good support via their helping team.
