Integer; Column: TColumneh); VarsortString: String; // Sort sequence begin // Sort with column dobeginif findName = ''.
case Title.SortMarker ofsmNoneEh: beginTitle.SortMarker: = smDownEh; sortstring: = Column.FieldName 'ASC'; end; smDownEh: sortstring: = Column.FieldName 'ASC'; smUpEh: sortstring: = Column.FieldName 'DESC '; end; // Drave Sort TryDataSet.Sort: = SortString // DataSet is the actual data set variable name excend; end; end; remember that the LookUp type field cannot be described above, otherwise the system will prompt the error.
