enter code here

string string_value= string.Empty;

        for (int i = 0; i < ur_grid.Rows.Count; i++)
        {
            for (int j = 0; j < ur_grid.Rows[i].Cells.Count; j++)
            {
                if (!string.IsNullOrEmpty(ur_grid.Rows[i].Cells[j].Text.ToString()))
                {
                    if (j > 0)
                        string_value= string_value+ "," + ur_grid.Rows[i].Cells[j].Text.ToString();
                    else
                    {
                        if (string.IsNullOrEmpty(string_value))
                            string_value= ur_grid.Rows[i].Cells[j].Text.ToString();
                        else
                            string_value= string_value+ Environment.NewLine + ur_grid.Rows[i].Cells[j].Text.ToString();
                    }
                }
            }
        }


        string where_to_save_file = @"d:\location\Files\sample.csv";
        File.WriteAllText(where_to_save_file, string_value);

        string server_path = "/site/Files/sample.csv";
        Response.ContentType = ContentType;
        Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(server_path));
        Response.WriteFile(server_path);
        Response.End();
