[flexcoders] Custom component itemRenderer
Is it possible to pass data into an itemRenderer that is not apart of the
dataProvider. The component I am using as an does not seem to except
bindable data when it's used as an item Renderer.
coursedays and unittypes are both arrayCollections from remoteObjects.
The itemRender is using data. from coursedays. But I also want to
pass in the arrayCollection of unittypes. Is this the correct opproach?
mx:HorizontalList id=days_hlist useRollOver=false width=980 height=570
borderStyle=none selectable=false horizontalScrollPolicy=off left=0
dataProvider={coursedays}
mx:itemRenderer
mx:Component
courseeditor:dayoutline unittypes={unittypes}/
/mx:Component
/mx:itemRenderer
/mx:HorizontalList

You must extend the component creating the itemRenderers and modify it to pass in your additional data. Most itemRenderers also have a ListData component, which has an owner attribute that give you hook into the list. So if you can get to your data using that owner property, it may work for you. Or you can create your own ListData component and modify your list based class to create your new ListData component instead of the built in one and pass that to itemRenderers. You may also be able to use a singleton, conceptually similar to Cairngorm's ModelLocator to access the data hanging out in the middle of nowhere. -- Jeffry Houser, Technical Entrepreneur Adobe Community Expert: http://tinyurl.com/684b5h http://www.twitter.com/reboog711 | Phone: 203-379-0773 -- Easy to use Interface Components for Flex Developers http://www.flextras.com?c=104 -- http://www.theflexshow.com http://www.jeffryhouser.com -- Part of the DotComIt Brain Trust

Speaking only from what I have read here, I believe if you set the renderer using ActionScript and the ClassFactory, you can set properties on the renderer. Ah, from one of alex's posts: If you look at ClassFactory, it has a properties map that will copy any properties in the map to each instance.
