Part 2 begins with a demonstration of a sample custom module, and a walk-through of the module source code layers to see how it works. During the tour, we'll look at implementation of the optional DNN interfaces including: IActionable, ISearchable, IPortable, IHydratable, and a discussion of IUpgradeable, and IPropertyAccess. We'll also look at localization techniques in the source, and basic module UI styling. Next is a tour of the DotNetNuke core from the developer's perspective: reusable controls, base classes, page navigation methods, core APIs, AJAX functionality through the ClientAPI, and client-side programmability through jQuery. During the tour, we'll cover some advanced development tips & tricks. This is a 300-level session - some experience with DotNetNuke will be assumed.
