Description
TDataSetErrorEvent is the type of event handler that occurs when TDataSet raises an exception.
TDataSetErrorEvent is the type of event handler that occurs when a TDataSet raises an exception. Working with TDataSets can raise exceptions when attempting to insert, update, or delete records.
The DataSet parameter specifies the dataset that generated the E exception, while the Action parameter should be set by the developer with one of the possible actions defined by TDataAction (daFail, daAbort, or daRetry).
