AS3 – mx:List with ItemRenderer Scrolling Problem

go here ItemRenderer class instances in AS3 are re-used when rendering objects in mx:List.

homework help financial statements For example, if you provide 500 elements to the list’s dataProvider, and only showing 10 rows in the list output, it will create around just over 10 instances of your ItemRenderer. And every time you scrolls the list, it will use the existing renderers to render those new elements in the list by simply calling the “set data” method. It will be up to you to update the state of the renderer yourself, otherwise you will expect very weird behaviours.
