Yeah it's easy :) To create a relationship between 2 datasets create a datarelation. Look in the Visual Studios help index for datasets, relationships Thier example is as follows. Dim CustomersOrders As New DataRelation("CustomersOrders", _ DsNorthwind1.Customers.Columns("CustomerID"), _ DsNorthwind1.Orders.Columns("CustomerID")) DsNorthwind1.Relations.Add(CustomersOrders) "People who never make mistakes, never do anything."
