how can handle enter pressing user ?
need perform actions when user presses enter in combobox. can add keydown event somehow or maybe cast iribboncontrol useful?

update :

made decision not include functionality. still interested in solution problem.

even windowselectionchange event wont you. works other key press not enter , backspace (as aware of).

you have use low level keyboard hook
