Answer 1

for i:=0 to DMsea1.Qche.RecordCount -1 do begin
  if DBGrid1.SelectedRows.CurrentRowSelected then
     ListBox1.items.add(DMsea1.Qche.Fields[0].asstring);         
       DMsea1.Qche.Next;
      end;

Answer 2

要那么复杂吗？选好Dbgrid,在ObjectInspector里头：
  Opitons->dgMultiSelect->True

Answer 3

不好意思，看错了，我想行应该有Selected标志吧

Answer 4

with DBGrid1, DBGrid1.DataSourece.DataSet do begin
  First;
  while not Eof do begin
    SelectedRows.CurrentRowSelected := True;
    Next;
  end;
end;

Answer 5

请线设置sgMutiSelect := true ;
procedure TCLCK_KCJZ_Form.b_SelectAllClick(Sender: TObject);
var
i:integer;
begin
    if tmxzjbb.Active then
    begin
        tmxzjbb.First;
        i := 0;
        while not tmxzjbb.Eof do
        begin
            dbg_mxzlb.SelectedRows.CurrentRowSelected := true;
            tmxzjbb.Next;
            i := i + 1;
        end;
    end;
end;

Answer 6

将与DBGrid相关联的DataSet移动到需要选定的记录，执行DBGrid1.SelectedRows.CurrentRowSelected := True;
就能选定该行。
提取时：with DBGrid1 do
begin
  For i:=0 to SelectedRows.Count do
  begin
    DataSource.DataSet.GotoBook(SelectedRows.Items[i]);
    ....
  end;
end;

Answer 7

dbg_mxzlb.SelectedRows.CurrentRowSelected := true;
if DBGrid1.SelectedRows.Count>0 then
    with DBGrid1.DataSource.DataSet do
      for i:=0 to DBGrid1.SelectedRows.Count-1 do
      begin
        GotoBook(pointer(DBGrid1.SelectedRows.Items[i]));
        for i := 0 to FieldCount-1 do
        begin
          s:=Fields[i].AsString;//提取记录
        end;
      end;
