How to find a value in sandgrid without iterating each row and their nested rows ?

How to find a value in sandgrid without iterating each row and their nested rows ? Is there any better way we can do this ? Could you please help me with this issue .

foreach (GridRow row in Form.KGrid.Rows)

                    {

                        var kRow = row.NestedRows;

                        foreach (GridRow cell in Row)

                        {

                            if (value.KId.ToString() == cell.Cells[0].GetValue().ToString())

                            {

                                cell.Cells[1].SetValue(true);

                            }

                        }

                    }
