As most of you may already know, Telerik OpenAccessORM uses the TrackedList<T> to manage the collection fields of its persistent classes. The objects that belong to such collection are in a 1-n relation with the parent object that ‘owns’ the collection. Before getting to the point of this post, let me put few words about the behavior of the TrackedList<T>. When a new object is added to a TrackedList<T>(ex: order.OrderDetails.Add(someDetail) ),Telerik OpenAccess ORM persists that object to the database. The new object has a reference to the owner of the collection to which it was added.  When one removes an object from...

The Microsoft Composite UI Application Block (CAB) is a framework used for creating Model-View-Presenter style windows forms applications. The Smart Client Software Factory (SCSF) streamlines the process of creating these applications by providing us with a powerful base project and a set of menu options for quickly generating modules, views, and events in Visual Studio.

Well... I like paraphrasing and what has happened before will invariably happen again :) The original phrase is of course Sumner Redstone's "Content is king". But why change it to "Code is king"? Only because this is the content, we, the developers create? Or is it because code is important and we should put more stress on it as developers? Both reasons are valid, but I will focus on the importance of code quality. There are a myriad of articles, blog posts, books, etc. about what defines “good code,” so I cannot add much to this topic. In a few words, I can just say that...

For those of you following this series, I'm going to take a slight detour to explain one of the little bits of magic that we have been using to make loading and saving appointments very easy: RecurrenceExceptionHelper.  If you downloaded the sample application from part 3, you'll see this sitting in the Silverlight-RIA-Entity folder (aka the Silverlight portion of the solution).  The first thing you might be asking is where the need for such a class comes from.  Well, handling Recurrence rules and Exceptions are two of the more complex things that you can do when working with appointments.  When...
