dataGridView with line break, however when exporting to excel it does not break

Galera,

I have a dataGridView that I used the following code snippet to break the text:

     dataGridView1.Columns[0].DefaultCellStyle.WrapMode = DataGridViewTriState.True;
     dataGridView1.Columns[1].DefaultCellStyle.WrapMode = DataGridViewTriState.True;

     dataGridView1.DefaultCellStyle.WrapMode = DataGridViewTriState.True;
     dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;
     dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None;

In the grid is working correctly, example of the string I am receiving:

  

"To the morning sun \ r \ n a drop of dew \ r \ n precious diamond."

When exporting to excel does not break text in the "SAME" cell and yes to the bottom line.

        xlWorkSheet.Columns[2].Cells.WrapText = true;
        xlWorkSheet.Columns[2].ColumnWidth += 15;
        //xlWorkSheet.Columns[2].AutoFit();
        xlWorkSheet.Columns[2].Cells.WrapText = true;
        xlWorkSheet.Columns[2].Style.WrapText = true;
        xlWorkSheet.Cells[8, 2].Style.WrapText = true;
        xlWorkSheet.Cells[9, 2].Style.WrapText = true;
        xlWorkSheet.Cells[10, 2].Style.WrapText = true;
        xlWorkSheet.Columns[2].WrapText = true;
        //Set Text-Wrap for all rows true//
        xlWorkSheet.Rows.WrapText = true;
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);          
    }

As you can see when breaking text to excel, it is not broken within the same cell but rather for new rows. How can I resolve this?
