he mirado y no, no tengo nada en esos eventos. ¿algo en la configuración del objeto?
Estoy usando un TADOQuery, pero tambien he probado con TADODataSet.

Esto es lo que tengo:

object TbADOAsisImport: TADOQuery
  Active = True
  Connection = ADOBDHyperion
  CursorType = ctStatic
  Parameters = <>
  SQL.Strings = (
    'select  *  from asistencias_todo'
    'order by codigo')
  Left = 544
  Top = 152
  object TbADOAsisImportcodigo: TAutoIncField
    FieldName = 'codigo'
    ReadOnly = True
  end
  object TbADOAsisImportgrupo: TIntegerField
    FieldName = 'grupo'
  end
  object TbADOAsisImportfecha: TWideStringField
    FieldName = 'fecha'
    Size = 50
  end
  object TbADOAsisImportnumalu1: TWideStringField
    FieldName = 'numalu1'
    Size = 50
  end

    Size = 50
  end
