In ActiveReports, in order to make your report output clearly visible during export or printing you can set character and line spacing. In order to use line spacing you must first set the MultiLine property for the control to True.
Line and character spacing is supported when you preview a report in the Viewer, print a report or export a section report in HTML , PDF and TIFF formats.
In page reports and RDL reports, it is also supported while rendering a report through rendering extensions in Word, HTML, PDF and Image formats. See Rendering Extensions for further information on rendering extensions.
