A different solution to display user messages in web apps

Web apps are very different from windows apps. One big difference is displaying messages to the user. In a windows app you can easily popup a message box and allow the user to click ok it or you can change the text in a status bar to let the user know something happened. Web apps don't have status bars and popup messages are difficult to do across pages. This solution is a mix between popup messages and a status bar for the web. Using a master page, some jquery JavaScript, and a few classes, you can easily and consistently display information and error messages to your users.
