you can use this simple code to accomplish

StringWriter sw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(sw);

    string attachment = "attachment; filename=SummaryReport" + DateTime.Now.ToString() + ".xls";

    Response.ClearContent();
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/ms-excel";


    grd.RenderControl(htw);

    Response.Write(sw.ToString());
    Response.End();

no need to save the file to the sever use the following code, will create the file on the fly:

Public Shared Sub DataTableToExcel(ByVal dt As DataTable, ByVal FileName As String
  HttpContext.Current.Response.Clear()
  HttpContext.Current.Response.Write(Environment.NewLine)
  For Each row As DataRow In dt.Rows
    For i As Integer = 0 To dt.Columns.Count - 1
      HttpContext.Current.Response.Write(row(i).ToString().Replace(";", String.Empty) + ";")
    Next

    HttpContext.Current.Response.Write(Environment.NewLine)
  Next

  HttpContext.Current.Response.ContentType = "application/ms-excel"
  HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment; filename=" + FileName + ".xls")
  HttpContext.Current.Response.[End]()
End Sub
