Use the LineNumberWidth property to show the control's line number width. Use the BookmarkWidth property to show the control's bookmark border. By default, the LineNumberWidth property is 0. If the control's LineNumberWidth is zero the control's line number border is hidden. If the LineNumberWidth property is 0 the control displays no line numbers border. If the LineNumberWidth property is less than 0 the control sets the width of the line numbers border automatically. Use the LineNumberBackColor and LineNumberForeColor properties to customize colors for the control's line numbers bar. Use the LineNumberFont property to specify the font for the control's line numbers bar.
