Hi Ram
Export to stream. See KBA 1198587 - How to export a report to stream in C Sharp (C#) for Visual Studio .NET
BTW., the reason you cannot see all the columns in the viewer is because the report engine depends on the printer driver.E.g.; say you'd need a page width of 30 inches to see all the columns, you'd need a printer driver that can print / supports a 30 inch paper width.
Alternatively, you can see what happens with the report is you check the "No Printer" option and "Dissociate Formatting Page Size and Printer Paper Size" option.
