Divide a Document into Sections

The Document.Sections property provides access to the document’s section collection. Use the following methods to insert a section in code:

Specify the Section.StartType property to define the section break’s type. The RichEditDocumentServer supports the following section breaks:

  • Next Page - starts the new section on the following page.
  • Continuous - starts the new section on the same page.
  • Even Page - starts a new section on the next even-numbered page.
  • Odd Page - starts a new section on the next odd-numbered page.
  • Column - starts a new section on the next column on the page.

Use the RichEditBehaviorOptions.PageBreakInsertMode property to specify whether a page break is inserted next to the specified position or in the new line.

Define Page Formatting Options

Each section has page formatting options. You can use the SectionPage class properties to specify the page’s paper type, orientation, margins, etc. Use the Section.Page property to access the SectionPage object .

The code sample below specifies the first section’s page formatting options: sets the portrait orientation and the A3 Extra paper size.

Section firstSection =  richEditDocumentProcessor1.Document.Sections[0];
firstSection.Page.Landscape = false;
firstSection.Page.PaperKind = System.Drawing.Printing.PaperKind.A3Extra;

Line Numbering

Set the SectionLineNumbering.CountBy property to a non-zero value to enable line numbering. Refer to the How To: Add Line Numbering topic for more information.


Call the SectionColumns.CreateUniformColumns method to create a multi-column layout. Refer to the How to: Create a Three-Column Layout with Uniform Columns topic for more information.

Page Numbering

Each document section has its own page numbering settings (page number format, initial number, etc.). Use the Section.PageNumbering property to access the SectionPageNumbering class properties and specify section’s page numbering options. You should reset the numbering options by setting the SectionPageNumbering.ContinueNumbering property to false before you apply new options. The PAGE field represents a document’s page number. To apply new settings to existing page numbers, call the FieldCollection.Update method to update all fields.

The code sample below specifies the initial number and the NumberingFormat.CardinalText numbering format.

richEditDocumentProcessor1.Document.Sections[0].PageNumbering.ContinueNumbering = false;
richEditDocumentProcessor1.Document.Sections[0].PageNumbering.FirstPageNumber = 3;
richEditDocumentProcessor1.Document.Sections[0].PageNumbering.NumberingFormat = NumberingFormat.CardinalText;

Headers and Footers

Headers and footers in the document belong to a particular section. You can use the Section.BeginUpdateHeader - Section.EndUpdateHeader and the Section.BeginUpdateFooter - Section.EndUpdateHeader method pairs to edit header or footer content. Refer to the Headers and Footers topic for more information.
