in the MS Access version of Northwind to get the Unit price on selected index change of product. they intoduce a GetListPrice in the code behind of Order Subform. Like:
Option Compare Database
Private Sub Product_ID_AfterUpdate()
'Initialize price and discount for each product change
If Not IsNull(Me![Product ID]) Then
Me![Quantity] = 0
Me.Quantity.Locked = False
Me![Unit Price] = GetListPrice(Me![Product ID])
Me![Discount] = 0
Me![Status ID] = None_OrderItemStatus
'Empty Product records mean user wants to delete line item
Now on the SQL server 2008 version there a similar database however everything seems to work somehow like a well oiled engine without the code behind. ummm...
How is this achieved automatically calling the ListPrice from the Product table based on OrderItem selected product. Am I missing s
mething? Can anyone demystify this?
