This sample C# ASP.NET Web application demonstrates how
to use the viewer's PrintMode property to specify how
client-side printing is to function. The PrintMode property allows client-side printing using
a PDF solution, or an ActiveX control solution.?The PDF solution involves displaying a pop-up browser window
with Print options to select the page range to print.
Once the page range is selected and the Print button is clicked,
the report is exported to PDF format on the server, and
streamed back to the client and displayed in the pop-up
browser window.?The ActiveX solution involves downloading and installing
a small client-side ActiveX control that will display a
Print dialog that contains the printer drivers configured
on the client's machine. Once a printer is selected, the
report is printed to that printer. A small window displays
the status of the report being printed.NOTES:
The following are known issues with this sample application:?When using the ActiveX option, the small pop-up window
cannot be disabled or modified.?The ActiveX solution requires a postback for each
