Editable datagridview

Question

i have a textbox and a datagridview . and the following code on the textbox keydown event

               case Keys.Enter:
                        {                           

                                datagridview1.Focus();
                                datagridview1.CurrentCell = datagridview1.Rows[0].Cells[0]; //                          
                              

                            }

                            e.Handled = e.SuppressKeyPress = true;
                            break;
                        }
                }
            }
        }

i have 2 problems here

1. regarding BeginEdit(true) : what is the ideal method for beginEdit(true) as my purpose is as soon as the datagridview gets in focus by any control on the form , it should be edit mode straight away . so what method should i choose
   Onenter method or OnCellEnter
2. i want that the datagridview's first cell of first column and first row should be the first cell by which the datagridview gets in editing mode . what should be better choice

dataGridView1.Rows[rowindex].Cells[columnindex].Selected = true;

or

datagridview1.CurrentCell = datagridview1.Rows[0].Cells[0];
