Asp.net Ajax Error Handling

ASP.Net Ajax is great for developing web applications. However there are some issues in presenting server side exceptions in the browser nicely. I actually needed the entire stack trace to be shown in the screen. Whenever I had an error while using Ajax, I used to get an alert with error message. Sometimes even I got notification in the status bar of the browser window. Instead of getting the error on the alert box, I wanted to get it on the body or label in the body of the browser window.
