Asynchronous update
The viewer allows the user to navigate pages using a thumbnail strip of the document and to pan and
zoom pages. Client-side actions result in server-side regeneration of images that are sent to the
browsers asynchronously. This provides the same user interface experience as a PDF reader plug-in.
Customize look and feel
The component includes a number of standard ASP.NET controls such as the page viewer, a thumbnail viewer and a toolbar. All controls can be customized through CSS and custom images.
Client-side JavaScript
The control also provides client-side JavaScript methods that can be used to retrieve document properties and initiate actions such as navigating to a given page or pan and zoom. This way, the developer can develop its own client-side UI and hook into the PDFWebViewer.NET control.
