Chapter 3. Using web part connections
This chapter covers:
Connections are powerful features of the portal framework that allow data to be exchanged between web parts. Connecting web parts can be fun because it provides you with an opportunity to think up interesting ways of presenting data to end-users. In this chapter we will learn about connections and the web part controls—such as the WebPartConnection—that make it possible for connections to occur. We’ll see that there are several ways to connect web parts, and we’ll also learn how to create and configure transformers to connect web parts that expose different interfaces.
