Note: This meeting falls on a Monday night, not the regular Tuesday.  This is an INETA-sponsored event.

This session is a deep dive into the ASP.NET AJAX UpdatePanel.  The UpdatePanel provides for a mechanism to add client side Ajax capabilities through a server side control.  We'll look at:

• Quick Intro to the UpdatePanel.
• How to debug with it.  The UpdatePanel provides client side Ajax functionality. We'll look at how to debug with it and see that the UpdatePanel allows for the server side debugging functionality that mostdevelopers are used to.
• Its client side programmability features.  The UpdatePanel provides a client side interface into its features. We'll look at the events provided and how they allow developers to add to their applications to improve the user experience.
• Error Handling.  By default, errors are generated as JavaScript alerts, we'll look at the options for handling errors so that user's aren't forced into the annoying JavaScript alert popup.
• The data format that the UpdatePanel uses.  When does AJAX not use XML or JSON for data transfer? When it the UpdatePanel is used.  We'll look at the Update Panel's data transfer format.
• History with the UpdatePanel. One of the most frustrating things from a user's standpoint is that hitting back on Ajax application takes them out of the application.  We'll look at what a developer must do so that a user hitting back does not exit from the application, but merely goes back to the previous state of the application.
