You should be able to display checkboxes in a normal listbox. You have to set the MultiSelect property of the listbox to true (Simple or Extended), then you should have the option of setting the Style property. (Normal or checked) Once you've done this, the list box will display a small check box inside the list, and when the user selects options from the list, the box is checked instead of the selection being highlighted.
Hope that's what you're looking for
