Report Builder 2.0 - Need to change chart size dynamically according to page size selected in page setup

Hi All,

I have created pie chart in Report Bilder 2.0.

Default size of chart is 9.82458in, 3.44792in, default page size in page layout is letter and landscape.

when we view chart in print layout , its working fine.

But when we change page size in page set up to for example executive or A5 or any other page size which is less than the size of chart then while viewing the chart in print layout option following error occurs -

"An error occured during local report processing.Parameter is not valid."

So I want to set chart size dynamically according to page size selected in page setup.

what should I do so that above error will not occur? I am thinking to set chart size dynamically.. but I don't know how to do that based on the page size selected in page setup.

Need help.

Thanks,
