No data retuned

Hi,
Does anyone know of a way to show a user that there is no data returned into a report from a query, I am using ASP.NET with reportviewer and if the report does not return data I want to tell the user and not let them wait for no response. Is there a method or property within crystal that I can use?CrystalViewer control provides two functions called GetCurrentPageNumber() and ShowFirstPage(). Using these two functions you could move your cursor to page 1 and then try getting Getcurrentpagenumber or either call GetCurrentPageNumber which if returns 0 then there is no data else there is a data.

Thanks
