Synchronize bindingList, DevExpress gridControl and database

Question

We have an application that uses three-tier architecture (client, server, database). On the client side there is a devexpress gridControl which is used to modify data . Its datasource is bindingList. The question is how to synchronize three entities:bindingList, gridView and database. We tried to hook up to bindingListChanged event when the new item is added but we faced a problem. This event is fired immediately after first key has been entered in the New Item Row. In that moment there is no data we can send to our database. Can you help us? What are the best practices to solve that kind of problem?

Thank you. Looking forward for reply.
