Hi!

Is there some sort of a standard or a guideline/matrix in selecting the best BO to use in a given setup?

e.g.

If the UI is grid based (Editable DatagridView) then which is the best BO(s) to use (BusinessBase and BusinessListBase)

If used in a dropdowncombo (NameValueList) etc.

Yes, your use cases, which should not mention the UI at all.

The use cases describe how the system should function. The system should function the same way regardless of the UI that's using the objects.

Typically though you end up using a grid when working with a BusinessListBase, and dropdown boxes usually use something deriving from NameValueList. Notice the wording though; the type of BO helps decide which UI component to use, not the other way around.

Hi!

Yes I agree with that a 100% but like you mentioned "the type of BO helps decide which UI component to use" and that's what I am looking for.

e.g.

BusinessListBase and BusinessBase -> DataGridView (BusinessListBase for the collection and BusinessBase for each row)

NameValueList -> Dropdown combo boxes

Yes, that'd be right. Usually BLBs are displayed in grids, NVL usually end up in dropdowns..
