I represent a directory structure with folders and documents that reside with a database;. The treeview is bound to a DataTable. I want to include additional properties that I can use in the On Node Data Bound event. With a GridView, I can add hidden fields to the Grid. I want to do the equivalent on the Treeview and include information such as the file type, its' creator, etc as additional non-visible fields within the TreeView when I bind it to the DataTable. All of the fields I want are columns in the table. I can't find any examples of how to do this. Help appreciated.
Thanks
