Declaration

public procedure TDataSet.Next;

Description

Next positions the cursor on the next record in the dataset. 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 last known record (EOF is true), then no action is performed, and the events are not triggered.

Errors

Calling this method on a closed dataset will result in an EDatabaseError exception.
