RAD PDF - Interactive Demonstrations

This basic implementation demonstrates how to use Lite Documents. Lite Documents do not use a database and allow for a simpler RAD PDF implementation. By default, Lite Documents use ASP.NET Session State to associate document keys with a given document instance. Using a PdfIntegrationProvider, a custom PdfLiteSessionProvider can be implemented to avoid relying on ASP.NET Session State.

Lite Documents have nearly all the functionality of normal RAD PDF Documents, but without relying on RAD PDF's SQL based storage. By default, Lite Documents are temporary. But you can use a custom storage provider to implement your own custom storage system to store documents as your application requires.

In many cases, Lite Documents can be used by simply replacing <PdfWebControl ... > with <PdfWebControlLite ... >.
