public property TCustomBufDataset.ChangeCount : Integer

Description

ChangeCount is a read-only Integer property that indicates the number of pending changes in the update buffers allocated for the dataset. Update buffers are maintained in an internal TRecordsUpdateBuffer member when methods that add, delete, or modify record data are called.

ChangeCount can be used in an application to determine if ApplyUpdates, CancelUpdates, or RevertRecord should be called prior to closing the dataset.
