Answer 1

Try this code for exporting to excel instead of what you are using. I use this for web apps though.

private void ExportGridToExcel()
{
    Response.Clear();
    Response.Buffer = true;
    Response.ClearContent();
    Response.ClearHeaders();
    Response.Charset = "";
    string FileName = "SomeFileName" + DateTime.Now + ".xls";
    StringWriter strwritter = new StringWriter();
    HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.ContentType = "application/vnd.ms-excel";
    Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
    GridView1.GridLines = GridLines.Both;
    GridView1.HeaderStyle.Font.Bold = true;
    GridView1.RenderControl(htmltextwrtter);
    Response.Write(strwritter.ToString());
    Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
    /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
       server control at run time. */
}

update the internal loop to be:

for (i = 0; i <= dataGridView1.RowCount - 2; i++)
            {
                for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
                {
                    Range range = (Range)xlWorkSheet.Cells[i + 1, j + 1];
                    xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1[j, i].Value.ToString();
                    range.Interior.Color = System.Drawing.ColorTranslator.ToOle(dataGridView1.Rows[i].DefaultCellStyle.BackColor );

                }
            }

don't forget:

using Microsoft.Office.Interop.Excel;
