As far as I know, you cannot open a new window in asp.net without using javascript. If you want, you can use Response.Redirect to go to a new asp.net page with your report. As for popup blockers, these can be turned off by the user for a specific site. If your application is for intranet use, then that would not be much of a problem. If your target audience is the general public, then perhaps it would be easier to redirect to a new web page.
