ListBox vs CheckBoxList

Aspect	ListBox	CheckBoxList
Presentation	Native list box	Group of checkboxes
Multi-select	Hold Ctrl — not intuitive for average users	Simply click to check
Footprint	Height controllable (Rows)	Grows with option count

Recommendation

For public-facing forms, prefer CheckBoxList for a more intuitive multi-select; ListBox fits cases with many options and limited space.
