The ListBox.ScrollAlwaysVisible property indicates whether a vertical scroll bar is always displayed, even if the number of items in the System.Windows.Forms.ListBox does not require displaying the vertical scroll bar. By default, a System.Windows.Forms.ListBox only shows a vertical scroll bar when there are enough items to warrant displaying. For a multicolumn System.Windows.Forms.ListBox, the ListBox.ScrollAlwaysVisible property indicates that a horizontal scroll bar is displayed. A vertical scroll bar is never displayed regardless of the value of this property for a multicolumn System.Windows.Forms.ListBox.
