I need to put ‘ExecuteNonQuery’ in this Command ?

 Dim CmdCertAut AS New SqlCommand("sel_CertAuto", strConnection)
 CmdCertAut.CommandType = CommandType.StoredProcedure
 CmdCertAut.Parameters.Add(New SqlParameter("@.Product_id", SqlDbType.smallint, 2, "Product_id"))
 CmdCertAut.Parameters("@.Product_id").Value = product.SelectedItem.Value
 CmdCertAut.Parameters.Add(New SqlParameter("@.Region_id", SqlDbType.smallint, 2, "Region_id"))
 CmdCertAut.Parameters("@.Region_id").Value = reg.SelectedItem.Value
 strConnection.open()
CmdCertAut.ExecuteNonQuery
 Dim Certif_Aut As SqlDataReader = CmdCertAut.ExecuteReader(CommandBehavior.CloseConnection)
 certAut.DataSource = Certif_Aut
 certAut.DataBind()
 Dim Cert_Aut As New ListItem
 Cert_Aut.Text = "(Select)"
 Cert_Aut.Value = "0"
 certAut.Items.Insert(0, Cert_Aut)
 certAut.SelectedIndex = 0

what are you trying to do ? bind the results of the stored proc to a datagrid ?|||Yes|||Then.. I need tho put it?
