However, since this is not my labelFunction I cannot return the name.

	private function trackLabel(item:Object, column:DataGridColumn):String {
                var url:String = pathString + item.@name;
		var sound:Sound;
                var soundLoaderContext:SoundLoaderContext;
                var urlRequest:URLRequest = new URLRequest(url);
                // Check policy file
                soundLoaderContext = new SoundLoaderContext(1000, true);
                sound = new Sound();
                sound.addEventListener(Event.ID3, sound_id3);
                sound.load(urlRequest, soundLoaderContext);
                return sLabel;
	}
        private function sound_id3(evt:Event):void {
                sLabel = Sound(evt.currentTarget).id3.songName;
                trace(sLabel);
        }

I believe the problem would be that (as far as I know) you need to _load_ the MP3 in order to access their ID3 metadata. So for your code to work you would need to have the label function try to load the MP3 and get the ID3 information. Or perhaps you could use a custom item renderer to do the same thing, but still, I don’t know that I’d try loading X number of MP3s simultaneously to get their ID3 information.

your blog is really one of the best on the web and I have been able to find the examples I need so far. But not this time.

I have mp3 urls in XML and I am using this XML as dataProvider of a DataGrid.
My problem is getting the labelFunction to display id3.songName instead of the url or filename.

Any ideas?

Best,

Are you using Flex 2 or Flex 3? I probably only tested Flex 3.
