The document discusses LiveBindings in Delphi XE2. It introduces LiveBindings as a technique to bind data to objects or components. It provides examples of using LiveBindings to bind dataset data to visual controls, bind properties between components, and bind dynamically created object properties to controls using expressions. The document also discusses the differences between managed and unmanaged bindings. It concludes with the contact information for Stefaan Lesage, who presented on LiveBindings.
