Dynamic itemRenderer in Flex

I was struggled last week about changing itemRenderer dynamically in flex...

at last its easy to change itemRenderer in actionscript..


import mx.core.ClassFactory;
Component.itemRenderer=new ClassFactory(RendererComponent);


here RendererComponent may be a mxml component ...or ActionScripr component..

if RendererComponent resides inside package mention it as com.somePackage.RendererComponent
