The RichEditControl provides the following ways to manage document sections:

Sections in the User Interface

You can insert section and page breaks and set the page layout options using the Page Layout ribbon tab. Refer to the How to: Create the RichEditControl with a Ribbon UI topic for information on how to add a Ribbon UI to the RichEditControl.

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


The RichEditControl ships with the Page Setup Dialog. This dialog allows end-users to define a page's formatting options of a whole document or a particular section.


Set the DocumentCapabilitiesOptions.Sections property to Hidden or Disabled to restrict end-users from managing document sections.

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 RichEditControl 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.

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 =  richEditControl1.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 Line Numbering topic for more information.

Line numbers in the Print Layout View are displayed automatically. Use the RichEditView.AllowDisplayLineNumbers property to show line numbers in Simple and Draft views.


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.


richEditControl1.Document.Sections[0].PageNumbering.ContinueNumbering = false;
 richEditControl1.Document.Sections[0].PageNumbering.FirstPageNumber = 3;
 richEditControl1.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.

Footnote and Endnote Options

You can specify footnote and endnote options for each document section. The Section.FootnoteOptions provides access to the footnote options, the Section.EndnoteOptions property retrieves the endnote options. Refer to the Footnotes and Endnotes topic for more information.
