    Creating a Gutter Margin
    In This Topic

    This topic uses "Gutter" report to demonstrate how to create gutter margins in a report.

    Gutter margins are extra space/margins added to a page layout required for binding. They make it easier to bind the pages into folders, brochures, etc. You can add a gutter margin to a report by adding the left margin on the pages, which changes on the basis of the currently displayed page. The gutter margin can be changed depending upon the type of binding you select.

    In this report, the value of Layout.MarginLeft property is changed on the basis current page number which creates a gutter margin where odd pages have a larger left margin. Perform the following steps to see how this can be done.
