I would like to prevent tabbing from one cell to another while a user is editing a cell.
override protected function keyDownHandler(event:KeyboardEvent):void
if (event.keyCode == Keyboard.TAB)
in my custom editor but it still tabs in and out.
I think you want to call preventDefault on the KEY_FOCUS_CHANGE event.
I have added a listener to item editor:
private function onKeyFocusChangeHandler(event:FocusEvent):void
but it still goes to next cell when I press Tab.
There are also methods that get called on the editor like save() and validate() that can return false and should retain the edit session.
