Databinding a Combobox

Hi All

I have a fairly simple thing I'm trying to do but for the life of me I cannot figure out why it's not working.

Working with VB.Net 1.0, Oracle 9i.

I have a stored procedure I'm calling to fill a dataset and then I want to bind the dataset to a Combobox.

Here's my code:

Dim ds As DataSet

            DB.OracleDataManager.AddCommandParameter("p_rcout", ParameterDirection.Output, Oracle.DataAccess.Client.OracleDbType.RefCursor, , True)

            ds = DB.OracleDataManager.GetDataSet("BISSETUP.SP_GET_ALL_CUSTOMERS", CommandType.StoredProcedure, True, "Customers")

           
            With cboCustomer
                .DisplayMember = "Cust_Name_Num"
                .ValueMember = "IND_CUSTOMER"
                .DataSource = ds.Tables("Customers")
            End With

The DisplayMember and ValueMember names are absolutely correct from the stored procedure.

When I run the form I get the value "System.Data.DataRowView" repeatedly in the combobox.

If I switch around the combobox settings, like move .DataSource = ds.Tables("Customers")
above the other two lines, the ValueMember field fills the combobox!

Can anyone tell me what I'm doing wrong?

Thanks
