Here's a question. The tutorials demonstrate dragging BOs onto forms and raise the suggestion that one might open other forms, e.g. a maintenance form, toi work on a record that is the current row in a BO on a search form. But - there is no example that demonstrates your preferred (or envisioned) method of linking the 2nd form to a BO. Do you put a separate one on the 2nd form and use a copydata function? Do you pass a reference to the BO on the first form? Does the DataLayer take care of this automatically somehow?



My inclination would be to create all of the BOs in some root form and then pass references to those BOs to each subordinate form as I create or activate them. Is this an acceptable/desireable approach?



What would you recommend?

I'm making a bit of headway on this. Are the listviews "bound" to the BO's? When I click on a row in the listview it does not seem to navigate to the corrensponding row in the BO like am used to with other databinging techniques that I have tried.



How do I do it? Is some kind of manual navigate call required?

When populating a listview an internal instance of the BO is dynamically created.  Even if you use the CopyDataFrom method, it is using the internal BO of the listview to populate itself.  To navigate a specific instance of a BO to another record place the following code in the SelectedIndexChanged event of the listview:

If MyListView.SelectedItems.Count > 0
    FormInstanceBO.NavigateToPrimaryKey(CType(MyListView.SelectedItem(0).Tag, Integer))
End If

Obviously you will need to make any necessary changes to match your PK value.
