How to limit the export file format

[Winla]

for Crystal reports for visual studio .net 2005, you can export the report
to various file format such as pdf, excel, word, rpt etc. If I just want to
limit the user see only excel and word format and set the default file
format to excel, is there a way to do it? Sometimes too many choose is
not good, is it?

I disagree the more choices the better. But i don't think its possible do modify Crystal Report Viewer to only offer the choices you want.
