• Writing and calling an Ajax-enabled WCF Web service
• Implementing the Ajax Accordion control

Enhancing Web Form controls with Ajax control extenders

• Creating modal dialogs with the ModalPopup control
• Simplifying dates with the CalendarExtender
• Responding to user input with the AutoComplete extender
• Guiding the user with TextBoxWatermark

Developing with jQuery

Manipulating HTML with jQuery

• Investigating jQuery syntax
• Returning wrapped sets with the jQuery function
