Odata4.0 expand multilevel

[RacketRebel]

what is the syntax for a multilevel expand in odata? for example the structure Customers, Orders, Details and i want to fetch some of the details.
dbservice.getCustomers("expand=Orders(expand=Details")?

New video: Three level hierarchy DataGrid using complex $expand parameter

Hi, I think this is not working anymore. I think it has to do with the latest OData changes on microsoft. [image] Or maybe it just works for the Blazor Server version.. which I guess would use linq include instead. I think it's related to this How do I expand to second level - #4 by korchev so my guess is we should use the dot notation for Blazor Server and the nested ($expand..) notation for ODATA sources

thanks it works, even with more than one extra level...

expand: "Levels , Levels($expand=Rooms, Rooms($expand=Surfaces))"
