Class: TEgDBGridEx
property OnGraphicError: TEgDBGridGraphicErrorEvent;Fired when a true ftGraphic field’s content cannot be
decoded as any of the supported image formats (JPEG, PNG, Bitmap, Icon,
GIF or Metafile). Does not fire for a plain BLOB field opted in via DetectBlobImages:
most BLOBs are simply not images, which is an expected outcome for such
a column, not a malfunction, so a failed decode there stays silent and
the cell falls back to the field’s own display text. The cell is left
blank either way for a true ftGraphic field; this event
only reports the failure. Msg holds a short, non-localized
reason. Also available at column level (see TEgColumn.OnGraphicError);
when both are assigned, the grid-level handler runs first. See TEgDBGridGraphicErrorEvent.
