WebDialogBox can be used in either StandAlone mode or Integrated mode. To enable the Integration mode, simply change the IntegratedToDesktopManager property to True.

When the WebDialogBox is integrated, the Window and Button styles of WebDialogBox will be inherited from from WebDesktop. Therefore, the consistent look and feel of all WebDialogBox can be maintained through out the entire application.  

One important thing to highlight is that when the WebDialogBox is integrated all the styles will be overridden with inherited styles from WebDesktop, this is to intended to ensure consistent look and feel of all Integrated WebDialogBox.
