Hi,

I would like to ask, what is the proper way to detect if the current record has been changed by another
user before posting back to the db?

To solve the specified issue, you can set the TUniQuery.LockMode property to lmPessimistic. If between dataset opening and the Edit method call the current record is changed by another user - UniDAC will generate the error message 'Record was changed by another user'.

Thank you
