I have a TreeView on the form with categories as the most top nodes with children subnode. Each child node has a BO PK stored in the Tag property. When user clicks on a child node, I am changing the position of BO by calling .NavigateToPrimaryKey(pkId), and all data-binded controls get refreshed.

Everything works great, but when the user clicks the top node (main Category), I want to clear all data-binded controls to indicate that no object is selected. How can I do that?

I would think that something like: bo.Navigate(BusinessNavigationDirection.Absolute, 0);
 or bo.Navigate(BusinessNavigationDirection.Absolute, -1) would work, but it has no effect on BO position.

Thank you
