Developer Express has a tutorial showing how the ExpressWeb Framework product from Developer Express supports WebSnap Adapters. Highlights include:

• full integration with WebSnap dispatching mechanisms
• visual display and drag/drop facilities for WebSnap Adapters
• powerful range of web controls and html elements available
• html designer (including html tags displayed/modifiable via Object Inspector)
• three way synchronization of dfm/pas/html files
• simple one key invocation of WebApp Debugger (also works for WebSnap without EWF pages)
• client side and server side events
• styles support via TcxWebStyleController (non-visual component which maintains a styles collection)
