Ok I have a report that has authentication that I pass through reportviewer. I have a link in this report a drill through report, problem is when I click on the link in the report viewer won't let me authenticate. I pass credentials through onDrillThrough event, but it still doesn't work. I would rather pass these network credentials from this reprot that were enterd to the drill through report. Their has to be a simple way to access the already authenticated login information and pass to the drill through report like I do with the other parameters in the jump to report action of the textbox. Any ideas I can't use a url because I am passing sensitive data that can't be seen or accessed by the user.
