Class: TEgFireGridColumn
property DetectBlobImages: Boolean;Whether a plain BLOB field in this column is also shown as a picture
when its bytes are one. A graphic field is always shown as a picture.
See the grid’s DetectBlobImages.
Until it is assigned, the column follows the grid’s DetectBlobImages,
and changes with it. Assigning it, even to the value it already shows,
gives the column its own value (cvDetectBlobImages in AssignedValues),
which the grid’s no longer changes; RestoreDefaults
makes it follow the grid again.
