You can bind to a strong typed collection that itself has a property which is another stringly typed collection. Take a look at this sample. \Essential Studio\3.3.0.0\Windows\Grid.Windows\Samples\Grouping\StrongTypedCollection
If you collections implement IBindingList, the grid should be able to automatically respond to changes. If your collection does not implement IBindingList, then you would have to somehow trigger the grid to redraw to see changes to your collections made outside the grid.
Currently, there is no way to load children on demand. If there were a flat table, 3.3 has some optimizations that allow it to more quickly handle large numbers of records, including a virtual mode that can be used in some situations. Here is a forum thread where teh user reported being able to handle 2.6M records using the 3.3 version. http://www.syncfusion.com/Support/forums/message.aspx?MessageID=34232
