TDataSet.Edit

Set the dataset in editing mode.

Declaration

Source position: db.pas line 1682

public procedure TDataSet.Edit;

Description

Edit will set the dataset in edit mode: the contents of the current record can then be changed. This action will call the TDataset.BeforeEdit and TDataset.AfterEdit events. If the dataset was already in insert or edit mode, nothing will happen (the events will also not be triggered). If the dataset is empty, this action will execute TDataset.Append instead.

Errors

If the dataset is read-only or not opened, then an EDatabaseError exception will be raised.
