I was working with the sample given for master detail and so far I have:

           ' Bind the master data connector to the Manual Order table.
           _masterBindingSource.DataSource = _dsManualOrder
           _masterBindingSource.DataMember =
_dsManualOrder.dtManualOrderItem.TableName

           ' Bind the details (order discount) data connector to the master
           ' data connector, using the DataRelation name to filter the
           ' information in the details table based on the current row
           ' in the master table.
           _detailsBindingSource.DataSource = _masterBindingSource
           _detailsBindingSource.DataMember =
_dsManualOrder.dtManualOrderItemDiscount.TableName

The problem is when I set the DataMember for the details (last step above) I
get an exception:

Message = "DataMember property 'dtManualOrderItemDiscount' cannot be found
on the DataSource."

I created some debug code to see what tables were available and:

           For Each dt As DataTable In _dsManualOrder.Tables
               Debug.WriteLine(dt.TableName)
           Next

Yields:

dtManualOrderItem
dtManualOrderItemDiscount

So I guess I am confused as to why the table is not found.
