This class represents a list box control. Use the Rows property to set how many rows you want to be displayed in the control at once (and hence, how much space the list box will occupy). You can also set the SelectionMode property to ListSelectionMode.Multiple if you want a user to be able to select more than one item from the list box at once.
Most of the list-specific functionality, such as determining the selected item and reacting to a SelectedIndexChanged event, is provided by the ListControl class, which ListBox inherits from.
