Description
Indicates whether the value for the BLOB field was changed since it was last read from the underlying database.
If the value of the BLOB field is set by using the properties or methods of TBlobField, the BLOB stream returned by a dataset's CreateBlobStream method, or a data-aware control, Modified is automatically set to True.
BLOB fields use the Modified property to trigger data events and to indicate when the dataset may need to clean up any buffers used to store BLOB data.
