EditableObjects.AcceptRejectChanges

Home / EditableObjects

After verifying the accuracy of changes made to the object, you can accept the changes using the AcceptChanges method of the object, which will set the Current field values to be the Original values. The RejectChanges method rejects all changes made to the object since AcceptChanges was last called.
