# TCustomBufDataset.CancelUpdates

Cancels pending updates in the dataset

## Declaration

Source position: bufdataset.pas line 635

`public procedure TCustomBufDataset.CancelUpdates; virtual;`

## Description

CancelUpdates is a procedure used to cancel pending updates to records in the dataset. CancelUpdates calls the CheckBrowseMode method to ensure that the dataset is Active, and to perform event notifications for a change in dataset state.

CancelUpdates checks for existing update buffers allocated in the dataset. When update buffers exist, the CancelRecordUpdateBuffer method is called for the bookmark in each of the update buffers.

CancelUpdates restores the record position when able, and calls Resync to refresh the records available in the dataset.
