How To: Add Line Numbering

The following example illustrates how to adjust line numbering to the specified document section.

To enable Line Numbering, set the RichEditView.AllowDisplayLineNumbers option for the current view to true and specify the SectionLineNumbering.CountBy property to a non-zero positive value.

In SimpleView and DraftView views line numbers are outside the default visible area, so you have to provide a space to display them by setting the left padding to a higher value (use the SimpleView.Padding or the DraftView.Padding property, respectively).

The line numbering font face and font color are specified by the Line Number character style.

To specify line numbering, the following properties are provided:

All the line numbering parameters can be accessed through the Section.LineNumbering property.

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E5219.

The following code snippet enables line numbering for the first section in the loaded document. Line numbering starts at number one and restarts at the new section. Numbers are displayed on each second line and are indented from the text at a distance equal to 0.25 of an inch.
