I can insert, update, delete the rows from grid when i am working with single table. But when i go for multiple tables i am facing problem in updateing and deleting the grid data. By using Mysql join, i am loading data, but i cant insert, update or delete rows.
How to solve this problem?

Thanks.

Hello,

Basic version allow one table DML operations.
For multiple table or complex business logic, you need to use custom on_update, on_insert, on_delete events, that are part of paid version.

Select sql will work fine with joins. Limitations is with DMLs.
