If you use an XmlListCollection, it will be able to display data hierarchically automatically. Else your domain model objects should implement the hierarchical data interface, a data grid accepts that interface as well.

This is not Flex classes, but kind of ORM system for user data. So I receive user data as from DB with a row like: Path (class4.class3.class2) - not like package, but true hierachical data. Class (Class1 which consists of Attributes (primitives), say Strings, Ints, etc) Need to build a Tree from that and put it in the 1st ADG column. I have 1000s of Classes, and it can go 10+ levels deep. So any idea how to build a tree (HierarchicalData) out of that (true hierarchical data, not grouping)? Any code samples? I created a POC, here is an exerpt of input data for a tree: [Bindable] public var acClasses:Object = { category:"root", children: [ new PathVO("class4", [ new PathVO("class3", [ new PathVO("class2", [ new ClassVO("Class1", { "Attr1", "Attr2", "Attr3"} ) ] ) ] ) ] ) }; Please advise! -- Thank you in advance, Oleg.
