Use nested views for this. You will have a dataview with the customer details but a datagrid for the orders of this customers. If your domain model das a one to many relation between orders and customer you will see you can use this datagrid to fill the relation. This way you will only see the orders from this customers and not from all the customers.
And take a look at the pizza mario case in the appstore. This will give you some insight.
