Exporting datagridview table to excel file

Below code works, but three minor issues:

1) No title row, how can I copy title row too (I mean field name row).

2) The data is pasted to cell B2, so output file column A is blank. It seems that the code also try to copy the blank grayed out column(with arrow and * ).  

3) What is the code to deselect the datagridview table(after pasting the data to excel)?

Thanks.

private void pictureboxExcelExport_Click(object sender, EventArgs e)
        {            
            copyAlltoClipboard();
            Microsoft.Office.Interop.Excel.Application xlexcel;
            Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
            Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;
            xlexcel = new Microsoft.Office.Interop.Excel.Application();
            xlexcel.Visible = true;
            xlWorkBook = xlexcel.Workbooks.Add(misValue);
            xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
            Microsoft.Office.Interop.Excel.Range CR = (Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[1, 1];
            CR.Select();
            xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);       
        }


        private void copyAlltoClipboard()
        {
            dgvTest.SelectAll();
            DataObject dataObj = dgvTest.GetClipboardContent();
            if (dataObj != null)
                Clipboard.SetDataObject(dataObj);
        }
