TDataSetEdit is a TDataSetAction descendant which edits the current record in the dataset for the target DataSource. TDataSetEdit ensures that the dataset is placed in edit mode (when available) by calling the Edit method for the dataset. Edit behavior is dependent on the underlying database engine.
TDataSetEdit publishes the DataSource property which explicitly declares the target for the database action. The DataSource may be determined by examining a data-aware control which used the database action, and passed an an argument to the UpdateTarget and HandlesTarget methods.
