Hi All,
I've been scratching my head here for a most of the day now,
I have a report viewer which will show a print preview of my report in Landscape, however when I print preview in Portrait I get an error..

"An error occurred during local report mode"
"Parameter is not Valid"

There is no more information, therefore I am kinda stumped to finding the source of the problem.

Has anyone else overcome this issue?
Does anyone know how I may be able to debug the error to find the source...

Thanks in advance..
