The GridView excels at showing a dense table with multiple rows of information. However, sometimes you want to provide a detailed look at a single record.

Microsoft Content Management Server Development : Building SharePoint Web Parts - Building the Presentation Layer

The Web Part needs to override methods provided by the SharePoint Framework in order to ‘hook in’ to the page request.

After that, the page and sub-channel listing will be displayed.

Microsoft Content Management Server Development : Building SharePoint Web Parts - Building the Data Layer

The Web Part will generate XML that lists all the ChannelItems in the configured StartChannel using the configured SortOrder. The use of XML facilitates the separation of the presentation layer from the data layer. Our data layer will be another class in the Web Part project but it could have been placed in an entirely different assembly for further abstraction.

Silverlight Recipes : Controls - Creating a Composite User Control

Silverlight offers two kinds of controls: user controls and custom controls.

ASP.NET State Management : Working with a Session's State (part 2) - Lifetime of a Session

The life of a session state begins only when the first item is added to the in-memory dictionary.

In spite of their quite unfamiliar names, the HttpApplicationState and HttpSessionState objects are state facilities totally compatible with classic Active Server Pages (ASP) intrinsic objects such as Application and Session. Ad hoc properties known as Application and Session let you use these objects in much the same way you did in ASP.
