Composite Controls

The third way to create a custom control is to combine two or more existing controls. In the next example, you will act as a contract programmer and we will act as the client. We’d like you to build a more complex control we can use to keep track of the number of inquiries we receive regarding our books.

As your potential client, we may ask you to write a control that lets us put in one or more books; each time we click on a book, the control will keep track of the number of clicks for that book, as shown in Figure 15-14.

To start, add to C15_UserControls a new web form called BookCounter.aspx. The complete listing for the content file is shown in Example 15-10.
