#43: How can I iterate the selected rows in DBGrid?

If your users can select a rows in the DBGrid, then you must navigate and process them. The TDBGrid component have a SelectedRows property, in which stores a list with bookmarks on each selected record.

var i: Integer;
begin
  for i := 0 to yourMDBGrid.SelectedRows.Count-1 do
  begin
    yourMDBGrid.DataSource.DataSet.Bookmark := yourMDBGrid.SelectedRows[i];

    {here you can process a selected record.
     For example, to sum the Amount field values}
    Inc(intSumAmount, yourMDBGrid.DataSource.DataSet.FieldByName('Amount').AsFloat);
  end;
end;
