I'm trying to create a hierarchical griddataboundgrid within which a user can expand and collapse nested relations. In the 'Essential Grid's User Guide' it says that one 'needs to just set the grid's data source to an ADO.NET DataTable of DataView with a foreign key and a relation. I've tried and I've tried but I cannot seem to create the right code.
Could you gimme an example of how to do this?
Please see the attachment to see the code I have till now.
Thnx in advance.
