"...create a custom component to encapsulate..." Yes, yes, yes. Though it is not clear what Gustavo wants, Steve is correct, this is the way to do Repeater.
Gustavo, The word/phrase "itemRenderer" has special meaning. itemRenderers are used with List-based components, and are tightly integrated with the framework, to optimize performance. Repeater's requirements are much looser, requiring only some component. (so the developer must watch performance). To take Steve's advice a bit further, pass a reference to the entire currentItem into the custom component. You can then code it normally, and can easily provide public properties to access in event handlers and such.

My understanding: You have XML that you are using as a dataProvider for a repeater; You want buttons to be created for each item in the dataProvider; Each button (When Clicked) should navigate to a URL based on data in the dataProvider. OK, if it were me, I would create a custom component to encapsulate each button. Here is an example: MyCustomButton.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:Button xmlns:mx="http://www.adobe.com/2006/mxml"; click="onClick(event)"> <mx:Script> <![CDATA[ public var theURL:String; private function onClick(event:MouseEvent):void { navigateToURL(new URLRequest(theURL), '_self'); } ]]> </mx:Script> </mx:Button> And an Application to use it: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="vertical" creationComplete="onCreationComplete()" xmlns:local="*"> <mx:Script> <![CDATA[ import mx.collections.XMLListCollection; [Bindable] private var buttonsXMLList:XMLListCollection; private var buttonsXML:XML; private function onCreationComplete():void { buttonsXML = <buttons> <button label="Apple" url="http://www.apple.com"/> <button label="Amazon" url="http://www.amazon.com"/> <button label="EBay" url="http://www.ebay.com"/> <button label="Adobe" url="http://www.adobe.com"/> </buttons> ; buttonsXMLList= new XMLListCollection(buttonsXML.button); } ]]> </mx:Script> <mx:Repeater id="buttonsRepeater" dataProvider="{buttonsXMLList}"> <local:MyCustomButton label="[EMAIL PROTECTED]" theURL="[EMAIL PROTECTED]"/> </mx:Repeater> </mx:Application> --- In flexcoders@yahoogroups.com, Gustavo Duenas <[EMAIL PROTECTED]> wrote: > > Hi I have a xml file and it has a <button1>800</button1> and so > forth, and also I have a repeater (a horizontal list) which grabs the > xml and the item renderer with a button, instead of doing the horizontal > list do the click I'd like to make the button inside the item > renderer to do that. > > how could I do that? > > I was trying to use > in the item rendered > > private function send():void{ > > <mx:Script> > <![CDATA[ > public function send(event:MouseEvent):void{ > var urlRequest : URLRequest = new URLRequest("{data.button1}"); > navigateToURL( urlRequest, "_self" ); > } > ]]> > </mx:Script> > > and in the button: click="send()" > > so far, it is just putting in my browser mybroser/{data.button1} > but I'd like to put in there the URL, how could I? > > Regards, > > Gus > > > Gustavo A.
