Description
Create Adobe PDF documents from your apps using ComponentOne PDF for .NET. The benefit of creating PDFs from your .NET apps is that you can essentially create databound PDF documents. This sample creates a Pdf file with NorthWind product information. Each product category is placed on a separate page and added to an outline structure with bookmarks.
