Description

Cancels modifications to the current record if those changes are not yet posted.

Call Cancel to undo modifications made to one or more fields belonging to the current record. As long as those changes are not already posted to the database, Cancel returns the record to its previous state, and sets the dataset state to dsBrowse.

Typically Cancel is used to back out of changes in response to user request, or in field validation routines that back out illegal field values. The TDBNavigator object contains a Cancel button that triggers a call to Cancel.
