The Placement property must be set to Custom for the callback delegate to be used.

The CustomPopupPlacementCallback delegate returns an array of possible points that are defined with respect to the PlacementTarget. When the context menu is displayed, a point is chosen that maximizes the amount of the ToolTip window that is visible.

The behavior is the same as it is for the popup. For more information, see How to: Specify a Custom Popup Position and Popup Placement Sample.
