However, I am using the TreeView as a Data Control because of it's nested hierarchy. It is perfect for things like projects/tasks and parts/assemblies because I can create a tree structure representation from flat data. To do this, I needed to be able to update the bizobj current field pointer when a new node was selected, so I went with an implementation specific solution that required the PK to be a field called "ID". It is definitely not the best way.
How do you update the bizobj current record within a dGrid object? Maybe I could model off of that and create a generic data aware TreeView object.
