If this is dvDefault, the value used is the one inherited from DefaultBlobDisplayValue.dvClass: Shows the class name in the display and edit modes.dvFull: Shows full text in the display and edit modes.dvClip:- In the display mode, it shows either full text or clipped text with '...' when the text length exceeds TField.DisplayWidth.
- In the edit mode, it shows full text.
dvFit:- In the display mode, shows either full text or class name when the text length exceeds TField.DisplayWidth.
- In the edit mode, it shows full text.
dvFullText: Show field value text for ftMemo or ftWideMemo; otherwise it will show the class name.
