Determines whether the list view displays a single line border.
property BorderStyle: TBorderStyle;
Use BorderStyle to affect the sharpness with which the list view control stands out on a form. BorderStyle can have a value of either bsSingle or bsNone. If BorderStyle is bsSingle, the list view is drawn with a single-line border. If BorderStyle is bsNone (the default value), there will be no border.
