i would like to use my AJAX-enabled VB web application's gloabal.asax application_error sub to manage all my error handling. However, instead of just sending the user to an error page, i would like to show the error message to the user via a modalpopupextender control located inside the site's master.page. Can someone please explain in detail how this can be accomplished? i have managed to do this using a single aspx page (with the modalpopupextender dynamically loaded there via a placeholder) and my errorhandler class raising the event to show the popup back on the page when an error occurs, but have not had success in doing the same using the master.page.
Thank you in advanced!
