How to create Role based Reports when working with ASP.Net Membership

Hi,

I have master page, menu on master page, i use asp roles and trim menu item based on user roles and rights this process is working fine.

Now i have to create some reports based on user roles, and responsibility in a company like country head will view country wide reports, manager region will only view regional report and rest will view reports related to them.

How can i achieve this efficiently using asp roles.

Thank You
