Thank you, works perfectly...

Thanks Bernard,  I'll take a look and will get back to you if I have any questions.

<isdatasource:isdatasource id="ISDataSource1" runat="server"    schematype="CustomObject" LoadOnDemand="True">

        <ISDataSource:ISDataSourceTable SelectMethod="getAllRDR" TypeName="RDRDetails"

            </SelectParameters>
        </ISDataSource:ISDataSourceTable>
    </tables>
</isdatasource:isdatasource>

Here is the function getAllRDR in the Class object:
    <System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, False)> _
        Public Function getAllRDR(ByVal _userID As String, ByVal _where As String, ByVal startRowIndex As Integer, ByVal maximumRows As Integer, ByVal sortExpression As String) As DataTable
        Dim reader As OracleDataReader = Nothing
        Dim oDT As DataTable = New DataTable()
        _where = Replace(_where, "AND ", "WHERE ")
        Using conn As OracleConnection = New OracleConnection(ConfigurationManager.ConnectionStrings("conn").ToString)
            Dim cmd As OracleCommand = conn.CreateCommand()
            conn.Open()
            cmd.CommandText = "data_access.get_all_rdrs"
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.Add("p_user", OracleDbType.Varchar2).Value = _userID
            cmd.Parameters.Add("p_where", OracleDbType.Varchar2).Value = _where
            cmd.Parameters.Add("p_start", OracleDbType.Decimal).Value = startRowIndex
            cmd.Parameters.Add("p_max", OracleDbType.Decimal).Value = maximumRows
            cmd.Parameters.Add("p_sort", OracleDbType.Varchar2).Value = sortExpression
            cmd.Parameters.Add("out_data", OracleDbType.RefCursor).Direction = ParameterDirection.InputOutput
            reader = cmd.ExecuteReader
            oDT.Load(reader, LoadOption.OverwriteChanges)
            reader.Close()
            Return oDT
        End Using
    End Function

When I put a breakpoint in the getALLRDR class an look at the parameters, startRowIndex and maximumRows is zero.

Not sure what I am missing here...

thanks

Thanks, I found out later that changing the doctype to xhtml showed correctly.

Thank You, I will take a look shortly.  Am in a release process at the moment.
