How to make auto refreshable web reports

When there is a need to reflect the current situation in your enterprise with the help of web reports, you might need to update information automatically on a site without any user's involvement. If you use more than one of these reports with auto refresh function on a single page of a web site, you get the “Dashboard”. Fortunately, FastReport provides auto refresh of a report by timeout.
