Click on any data row and it will become highlighted. Linked detail records will be displayed at the bottom of the page.
Sometimes it may be desirable to highlight the first row in the master view automatically.
Start the application generator, click on the project name, choose Design, and select the master data view of the page in Project Explorer.

Click Browse button on the tool bar to view the page in the web browser.
