Brian,

>It’s a winforms app. I can and have set the the NavControl property to the listbox, it just doesn’t do anything. I have a lstbox bound to a BO along with some textboxs. When I select records in the listbox the current record doesn’t change. All the textboxs still display the data from the 1st record. Compairing the mm code for the dataview grid and the listbox it looks like the listbox may not have all the pluming required to work as a nav control. Have you found this to be the case?

That's right, the ListBox doesn't have all the necessary plumbing.
