Viewing Live Data Within Dreamweaver

After you add dynamic information to a Web page, you see something like this in the document window: {rsAdsIndex.adID}. It gives you an idea of what the information is—in this example, the database column adID from a recordset named rsAdsIndex—but it doesn’t show any real database information, which can make designing a page more difficult. You’re especially far from seeing the actual result when a page contains a repeating region. What appears as a single row of dynamic text will actually appear as multiple rows or records when viewed in a Web browser.

Fortunately, you can preview a page with real database records directly in Dreamweaver. In addition to Design view and Code view, Dreamweaver includes one view expressly for working with dynamic information: Live Data view. When viewing a dynamic page in Live Data view, Dreamweaver contacts the testing server, retrieves recordset data from the database, and displays it in the document window (see Figure 22-13).

This is the Live Data view of the dynamic table pictured in Figure 22-9. Now you can update the data on the page by clicking the Refresh button. Turn on Auto Refresh if you want Dreamweaver to update this view automatically whenever you make a change to a dynamic element of the page (but avoid it if your connection to the testing server is slow). If refreshing the data takes too long (or Dreamweaver seems to freeze), click the Stop Live Data Update button to halt the current update.
