I'm going to try to combine your other response as well.
Yes, the repeater lets you dictate what the data items are and the same is true for item renderers. Normally, you plug a collection or array or xmllist into a List/Tree/DataGrid, etc and the items in that collection become the data properties in the renderers. The renderers job is to pull fields from the data object and stuff it into UI widgets in a renderer. I'm a codehead, and while I've given many talks about itemrenderers at MAX and other venues, it is an entire hour presentation and assumes you're up to speed on object oriented programming and actionscript, and trying to distill this topic into an email on FlexCoders is outside my time constraints right now. I generally respond to these emails while waiting for builds and regression tests to run, and give short answers when I know others on the forum can fill in the details. Sounds like you're hitting a pretty straightforward issue dealing with actionscript. If you post your code, I'll try to take a look at it on my next pass through this forum (as a true codehead, it is often easier for me to read code than your description). Also see some code I helped with in this forum yesterday with the subject "DataGrid cell access question" -Alex ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of droponrcll Sent: Saturday, September 29, 2007 12:17 PM To: [email protected] Subject: [flexcoders] Re: MultiPurpose ItemRenderer --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > There is a recommended pattern involving calling invalidateProperties() > in the .data setter, overriding commitProperties() to handle > distributing the data, and other "component lifecycle" methods. > > There is documentation on making custom item renderers, and you can look > at the source code for mx.controls.listClasses.ListItemRenderer and > mx.controls.TextInput and other mx.controls that are IListItemRenderers. I looked at the source for ListItemRenderer, and when I tried to do the same thing, I got 1024: Overriding a function that is not marked for override. When I added override, I got incompatible override. Clearly there is something here that I am missing. Please keep in mind that I am a Community Expert for Authorware, which means that for the past several years the people who have answered what questions I've had have been instructional designers first, codeheads second. So please try to imagine you are in front of a classroom of people who are relatively new to Flex and couch your answer in those terms. Thanks; Amy
