Finally, you learned how to annotate the map using the
built-in pushpin technology. We just scratched the surface of the capabilities of the feature-

CHAPTER 9 ?– AJAX-STYLE MAPPING USING THE VIRTUAL EARTH SDK 224
Building a Sample Application
Using ASP.NET AJAX
Throughout this book, you??™ve been exploring some of the underpinning technologies of
ASP.NET AJAX, including the client-side JavaScript libraries, which are object-oriented
additions to JavaScript. You??™ve also seen the power of ASP.NET AJAX server controls and
the ease with which they can be used to add asynchronous update functionality to an
ASP.NET page. In addition, we explored the rich set of UI controls and extenders offered
as part of the ASP.NET AJAX Control Toolkit. Lastly, we reviewed the Virtual Earth SDK,
and you saw how to add AJAX-style mapping functionality to your web applications.
In this chapter, you??™ll go through, in detail, what it takes to build an application that
makes the most of these features to deliver a real-world application.
