>Anyone has any idea how to make arrow on combobox without showing any scroll bar, once, by coincidence, the list was dropped from combo without any scrollbar on the right of the list, it's only show up arrow on the top of dropped list and down arrow below, but when I tried it again, it didn't happen anymore.

Hello Senna,

Scrollbar appears only when items do not fit in current display area. You must have experianced it when there are few items in it.
