Kevin,

All along, I assume that moving up and down a grid alone causes the navigation event to fire, which, I understand now, is wrong. Let me modify the jump start application as described in the Dev Guide in order to show what I need.

On the CustomerOrderForm, I decided to pull all customers (through a customer biz object) into grdCustomer when the form initially runs. I set NavControl to grdCustomer so that the grdOrder will be populated with the right orders for that customer when it is selected in grdCustomer. This I can do.

What I want is: if I select an order in grdOrder, I want the correct orderDetail records to be shown in grdOrderDetail. This I don¡¯t know.

I just found in the Dev Guide that Navigating and Navigated Events are raised from mmBusinessForm. I wonder why there is no record row changing and changed events raised from with in the business object.

Regards,
Chen
