how they do that? 'customer details' form in northwind 2016
the general tab displays customer info as to be expected in the form design.
the orders tab in design mode is another form with a horizontal list of labels and data,
however in practice when the orders tab is invoked, it displays a grid of orders,
the same grid which is the subdata sheet for the customers file, the order data is not
there populating the form fields as shown in design mode.
I don't where or how the form seen in design mode is replaced by the grid of the customer file subdata sheet?
this is the 'orders' tab form in design mode
the is the data grid displayed when the orders tab is selected
