GridGroupingControl and Custom Object Collection

[John Patterson]

I am utilizing the GridGroupingControl and a custom object model. When utilizing a DataSet with (n) tables and defining relationships between the tables, the GridGroupingControl will automatically build the hierarchy and allow expansion/collapsing of the parent/children data elements.

Is there a way to achieve similar behavior when utilizing a custom object model? It seems to me that the GridGroupingControl relies on the DataRelationCollection of the DataSet in order to generate the hierarchy, and I have not yet determined a way to duplicate the functionality when an object model is implemented.

I know that the GridDataBoundGrid will support custom object hierarchies, but it seems to only work when there is a single parent/child relationship at each level (i.e. parent object has collection of child A objects, which has a collection of child B object, which has a collection of child C objects), but does not work the same when a given parent has multiple children collections at the top level (i.e. parent object has collection of child A objects, collection of child B objects, and collection of child C object).

Any assistance you can provide is appreciated.
