Public ReadOnly Property changeEx As System.Object

public System.Object changeEx { get; }

public: __property System.Object get_changeEx();

public:
property System.Object changeEx {
   System.Object get();
}

For the combo box, changeEx is only available if the pop-up list is used-that is, a selection (with the mouse or the keyboard) is being made from the list. If the combo is editable and the user types in an entry, the Field/Keystroke event behaves as for a text field (that is, there are no changeEx or keyDown event properties).
