Unidbgrid and ClientDataset

[grib]

I have tested UniDBGrid connected with TClientDataset. I need to refresh some arbitrary rows without scrolling UniDBGrid:

 

  with ClientDataSet do

  begin
    iIndex := RecNo;
    DisableControls;
    try
      First;
      while not EOF do
      begin
        Edit;
        for cb2 := 0 to FieldCount - 1 do
          Fields[cb2].AsWideString := 'New' + cb2.ToString;
        Post;
        Next;
      end;
    finally
      EnableControls;
    end;
    RecNo := iIndex;
  end;

 

After execution this code the UniDBGrid is not updated. Shouldn't I use DisableControls? It works good even without it
