xdataset and updaterecord

there is anyway to update a record just inserted in DB ? if i have a identity-progressive field on the table i nedd to retrieve the value when just inserted. Or there is other way like rawinvoke for example to call a service on server ?

If the field is mapped as the id of the entity, the TXDataWebDataset retrieves it automatically after an insert. If it's a different field, that you will have to do it manually by performing further requests to the server asking the specific information you need.
