Hi,
I am learning radzen by migrating a complex form from our legacy application. Our requirement is to add multiple rows in multiple tables on submit.
I could successfully do this using the Invoke Custom Method. A few points which If I may suggest below :-
- Query Builder : This tool is useful for people not fluent in LINQ. Can it support multiple table join , advanced filter with group by etc.
- When we insert/delete rows from multiple tables using custom method can it support transaction processing with roll back on failure.
- Can runtime errors be displayed on pages itself as notification by default .i.e all error messages notified on pages itself if not handled
Regards,

Hey @Vinod_Pillai,
Multiple table joins are handled with $expand parameter separated with comma.
Since it's your custom method you can implement it in the way you want - transactional or not.
I guess you can catch global window.onerror and display the exception in the way you need.
Hey Thanks for the update

I am calling the custom method on save/submit button click event. First the basetable row is inserted by the submit button then my custom method is fired.
ex: table1 -> row inserted by save/submit button
table2,table3 -> rows inserted by custom method
if table1 or table2 or table3 insert fails all inserts should rollback.
Could you please elaborate how to handle transaction processing in such scenario.
