While ListBox and ComboBox continue to work in Windows 8, their use is discouraged. They are not designed well for touch input and there are new and more powerful controls in WinRT that you can use instead; specifically the ListView and the GridView.
ListView and GridView both derive from ListViewBase, and neither adds any properties, methods or events; thus they are nearly identical. The key difference is that ListView is typically used for vertical scrolling, while GridView makes a grid that is typically scrolled horizontally.
