Automatically Generating PDFs With Reports Requiring Parameters

Hi,
I'm working on many reports that are generated using SQL Server
Reporting Services SP 1 from an ASP.NET 1.1 web application. One of the
things the users would like to do is have the report automatically
generate a PDF when they click on the View Report button after entering
the parameters for the report. Parameters could be a date, a city, a
state, etcetera. However, they would like to avoid having to choose the
format and click the Export link. Is there a way to manipulate the
functionality of the View Report button such that it does this
automatically? Thank you for any insights you can provide.
JabooHow are you accessing the reports?
