Declaration

Source position: db.pas line 1733

public property TDataSet.State : TDataSetState read FState;

Description

State determines the current operational state of the dataset. During it's lifetime, the dataset is in one of many states, depending on which operation is currently in progress:

If a dataset is closed, the State is dsInactive.
As soon as it is opened, it is in dsBrowse mode, and remains in this state while changing the cursor position.
If the Edit or Insert or Append methods is called, the State changes to dsEdit or dsInsert, respectively.
As soon as edits have been posted or cancelled, the state is again dsBrowse.
Closing the dataset sets the state again to dsInactive.

There are some other states, mainly connected to internal operations, but which can become visible in some of the dataset's events.

TDataset.Active		Is the dataset open or closed.
TDataset.Edit		Set the dataset in editing mode.
TDataset.Insert		Insert a new record at the current position.
TDataset.Append		Append a new record to the data
TDataset.Post		Post pending edits to the database.
TDataset.Cancel		Cancel the current editing operation
