Hi, > I want to show 1000 items in the list .But it was taking so much time.
A list should easily be able to cope with a 1000 items and I've used a lists with 100,000 item without issues. It may be an issue with your item render. Can you post some sample code so we can see what is going on. Also try running your code through Scout or the Flash builder profiler and check to see where the issue is. Thanks, Justin PS This is probably a better question for the user list as it's not about the development of the Flex SDK.
