@Paul,

You can extend the ComboBox class, override the protected keyDownHandler() method and just filter those keys before calling super.keyDownHandler(), as seen in the following example:

 
package comps {
    import flash.events.KeyboardEvent;
    import flash.ui.Keyboard;
 
    import mx.controls.ComboBox;
 
    public class CustomComboBox extends ComboBox {
        public function CustomComboBox() {
            super();
        }
 
        override protected function keyDownHandler(evt:KeyboardEvent):void {
            switch (evt.keyCode) {
                case Keyboard.PAGE_DOWN:
                case Keyboard.PAGE_UP:
                    // abort
                    return;
                default:
                    super.keyDownHandler(evt);
            }
        }
    }
}

@av,

In the above example/SWF I don’t even see it acknowledging the arrow keys. Are you using different code?

When I iterate the combobox list using down arrow, every alternate/2nd item in the combobox is highlighted, instead of every item. Why is an item in the middle being skipped? Any clues?

Thank you
