The headers and footers are used to add repetitive information to each page of the document. They may
contain elements such as page numbers, dates, chapter titles, logos, and contact information. This helps
to improve document navigation and provides important information on each page.
In SautinSoft PDF .Net and Document.Net can easily add headers and footers to PDF or DOCX documents.
Below is an example code for adding a header and footer to a DOCX document using PDF .Net:
HeaderFooter header = new HeaderFooter(dc, HeaderFooterType.HeaderDefault);
header.Content.Start.Insert("Modified : 1 April 2020", new CharacterFormat() { Size = 14.0, FontColor = Color.DarkGreen });
foreach (Section s in dc.Sections)
{
if (s.Blocks.Count > 0)
s.Blocks.RemoveAt(0);
s.HeadersFooters.Add(header.Clone(true));
}
