Any suggestion to handle multiple level of tables editing? For example Invoice Heading → Invoice Detail → Shipment Details. I checked your demo about “Orders”. But it hasn’t any coding for saving. I have some confusing how to handle the new records and edit records. Should I use “Delta” feature to handle the data from client to server? Any example or demo about this? I’m using Devexpress cxGrid for user edit the detail records.
master.ApplyUpdates(); is enough.
it will send updates of master and all details tables to server.
I’ve attached old DA4 sample: MultiLevelDetail.zip (40.3 KB)
Note: it may require some manual changes because we’ve done refactoring in DA8 …
Noted with thanks. I will learn from your sample first.
