public procedure TDataSet.Prior; |
Prior moves the cursor to the previous record. It is equivalent to a MoveBy(-1) operation. Calling this method triggers the TDataset.BeforeScroll and TDataset.AfterScroll events. If the dataset is located on the first record, (BOF is true) then no action is performed, and the events are not triggered.
Calling this method on a closed dataset will result in an EDatabaseError exception.
