I have an application that requires a 3-level DataGrid hierarchy. I began by trying to duplicate the results of this video: New video: Three level hierarchy DataGrid using complex $expand parameter
When I get to the step to autogenerate columns (at the 2:01 time mark on the video) nothing happens -- no columns are created. Has something changed in Razden Profession that now requires an additional step?
I am using Northwind database in MS SQL Server 2019, Razden Pro 2.56.9, and created a server-side Blazor projects using .Net 5.
