Here is my code to generate xls file from gridview

C#

Response.Clear();
        Response.AddHeader("content-disposition", "attachment;filename=Contacts.xls");
        Response.Charset = "";
        Response.ContentType = "application/vnd.xls";

        StringWriter StringWriter = new System.IO.StringWriter();
        HtmlTextWriter HtmlTextWriter = new HtmlTextWriter(StringWriter);

        Grv_Data.HeaderRow.Style.Add("background-color", "#FFFFFF");
        for (int i = 0; i < Grv_Data.HeaderRow.Cells.Count; i++)
        {
            Grv_Data.HeaderRow.Cells[i].Style.Add("background-color", "#507CD1");
            Grv_Data.HeaderRow.Cells[i].Style.Add("height", "20");
        }
        int j = 1;
        foreach (GridViewRow gvrow in Grv_Data.Rows)
        {
            gvrow.BackColor = System.Drawing.Color.White;
            if (j <= Grv_Data.Rows.Count)
            {
                if (j % 2 != 0)
                {
                    for (int k = 0; k < gvrow.Cells.Count; k++)
                    {
                        gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
                    }
                }
            }
            j++;
        }

        Grv_Data.RenderControl(HtmlTextWriter);
        Response.Write(StringWriter.ToString());
        Response.End();

Hope this helps a lot...

Enjoy Coding...
