Append information to Excel file on GridView Export in ASP.NET C#

Question

I'm exporting a GridView to Excel with the following code:

protected void export_OnClick(object sender, EventArgs e)
{

    string style = @"<style> .text { mso-number-format:\@; } </style> ";
    // Let's hide all unwanted stuffing
    GridView1.AllowPaging = false;
    GridView1.AllowSorting = false;

    // Let's bind data to GridView
    BindGrid();

    //Change the color back to white
    GridView1.HeaderRow.Style.Add("background-color", "#ffffff");


    //Apply color to the header
    for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
    {
        GridView1.HeaderRow.Cells[i].Style.Add("background-color", "#e0e0e0");
    }

    // Let's output the Gridview
    Response.Clear();
    Response.ContentType = "application/vnd.xls";
    Response.AddHeader("content-disposition", "attachment;filename=" + reportid + ".xls");

    StringWriter swriter = new StringWriter();
    HtmlTextWriter hwriter = new HtmlTextWriter(swriter);

    GridView1.RenderControl(hwriter);

    Response.Write(style);
    Response.Write(swriter.ToString());
    Response.End();

}

Now I need to append a Name on the first row, Date & Time on the second row and possibly some other information on the third row. I will also like to leave a row between the actually GridView data and this information. Is this possible? If so, would you be so kind and provide some examples on how can I accomplish this. Thank you.

Just go ahead and add it. Add a carriage return after each to make Excel advance to the next row (use tabs to advance to the next cell).

Response.Write(style);
Response.Write("Pretty Excel Export File\n");
Response.Write("Generated on " + DateTime.Now.ToShortDateString() + "\n\n");
Response.Write(swriter.ToString());
Response.End();
