I have created a Listbox that remains hidden until the textbox above it gains focus. The idea being to minimize screen real estate when the list box is no in use. What I need to make happen, however, for my particular view, is to have the Listbox (when it becomes visible) span across a grid that is positioned below it. Is this possible to do? How? Combo boxes will display across other grids when they are opened. That is pretty much what I need to achieve with a Listbox.....
