AdvancedListBase

The UIDUtil class is a utility class for manipulating UIDs (universal identifiers) in Flex. A UID is a very unique String which is hopefully fully unique. The UID is intended to be a unique index to a particular instance of a class in Flex. The UIDUtil class has static methods that can create and fetch UIDs for any Object in a Flash application. UIDUtil is commonly used by the list classes to index their contents and provide lookups for various purposes.

The AdvancedDataGrid is a new class available in Flex 3 as part of the data visualization package. You can experiment with the AdvancedDataGrid without owning the correct license, but you'll get a watermark above every grid.
