Export GridView to PDF with Header Repeated on each Page in ASP.Net

Here Mudassar Ahmed Khan has explained with an example, how to export GridView to PDF with Header Repeated on each Page using iTextSharp in ASP.Net with C# and VB.Net. When the Export Button is clicked, a loop will be executed over the GridView Pages using PageCount property and GridView records for specific Page will be added to a new page of PDF. Thus, using this technique each Page of PDF will have records of one Page of GridView with Header.
