Add a web viewer to your layout. One way would be to add a new tab panel to your tab control to which to add the viewer. Set up the web viewer to refer to the Website field for the URL.
Click the web viewer tool and draw a rectangle where you want the viewer. In the Web Viewer Set Up dialog that appears, select Custom Web Address, select and delete all text in the Web Address box. Then click Specify and select the Web Site field shown in your screen shot.
