Hi Experts,

I use one Stored Procedures to fill two dropdown list boxes:

Dim myConnection As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim myCommand As New SqlCommand("GetCodes", myConnection)
myCommand.CommandType = CommandType.StoredProcedure

   Dim result As SqlDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
   Return result
Catch Ex As Exception
   Return Nothing
End Try

And my databind is:
Dim SNs As SqlDataReader = CodesDB.GetAvailableCodes()

dlstSN.DataSource = SNs
dlstSN.DataTextField = "SN"
dlstSN.DataValueField = "ID"
dlstCodes.DataSource = SNs
dlstCodes.DataTextField = "Code"
dlstCodes.DataValueField = "ID"

Then I got the "Invalid attempt to call FieldCount when reader is closed." error on the second databind.

Please help.
