# TDataSet.State

Current operational state of the dataset

## Declaration

Source position: db.pas line 1351

`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.
