Description
Occurs when a provider can't update a record because of an error condition.
Write an OnUpdateError event handler to respond to error conditions that arise when the provider applies a client dataset's updates. The OnUpdateError event handler is called for each record that can't be updated.
Warning: The provider can't detect when an update conflicts with another user's changes to a memo field. This situation will not generate an OnUpdateError event.
OnUpdateError is an event handler of type Datasnap.Provider.TResolverErrorEvent.
