ReportViewer Render Excel 2007

[verosb]

Necesito exportar a Excel 2007 en lugar de a Excel 2003 un LocalReport.ReportViewer (rdlc), ¿hay alguna forma de hacerlo?

Si no es así, ¿alguien podría decirme un control similar al ReportViewer que podría utilizar?

He leído en otros foros que con el siguiente código debería funcionar pero no es así...

Dim warnings As Warning()
Dim streamids As String()
Dim mimeType As String
Dim encoding As String
Dim extension As String
Dim filename As String

Dim bytes As Byte() = ReportViewer1.LocalReport.Render("ExcelOpenXML", Nothing, mimeType, encoding, extension, streamids, warnings)

filename = String.Format("{0}.{1}", "ExportToExcel", "xls")
Response.ClearHeaders()
Response.Clear()
Response.AddHeader("Content-Disposition", Convert.ToString("attachment;filename=") & filename)
Response.ContentType = mimeType
Response.BinaryWrite(bytes)
Response.Flush()
Response.End()

El error que me aparece es el siguiente:

Specified argument was out of the range of valid values.
Parameter name: format
