Repeater is not List and does not have automatic selection functionality. You want to have a click on the repeated item call a handler function and then do some work.
Below is some sample code. Tracy Goal: Display a list of items using a complex display for each item, and have each of those items behave like a menu element and respond to a click anywhere on the item by running a handler function. One solution is to use a Repeater with a custom component In the main app or component, declare the Repeater, and the click handler function. <mx:Application ... <mx:Script><![CDATA[ import MyRepeaterItem; ... private function onRPItemClick(oEvent:Event):void { var xmlItem:XML = XML(oEvent.target); }//onRPItemClick ]]></mx:Script> <mx:VBox ...> <mx:Repeater id="rp" dataProvider="{_xmlData}" ...> <!-- Note we pass in the entire currentItem, and define a click handler --> <MyRepeaterItem xmlItem="{rp.currentItem}" itemClick="onRPItemClick(event)" .../> </mx:Repeater </mx:VBox> </mx:Application> And in the component, MyRepeaterItem.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:HBox mouseChildren="false" buttonMode="true" click="onClick(event)" > <!-- The metadata tag below allows us to define an itemClick handler in mxml, as in the code above --> <mx:Metadata> [Event(name="itemClick", type="flash.events.Event")] </mx:Metadata> <mx:Script><![CDATA[ [Bindable]private var _xmlItem:XML; /** Setter function */ public function set xmlItem(xml:XML):void { _xmlItem = xml; //do any special, non-bound ui stuff you want }//set xmlItem /** Getter function */ public function get xmlItem():XML { return _xmlItem; }//get xmlItem /** Outer VBox Click handler function */ private function onClick():void { dispatchEvent(new Event("itemClick",false); //we do not need/want this event to bubble }//onClick ]]></mx:Script> <!-- Now declare the Item UI --> <mx:Text id="lbDescription" text="[EMAIL PROTECTED]" width="100%" height="100%" /> </mx:HBox> From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of abhishekchess1 Sent: Tuesday, October 16, 2007 4:21 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] how to catch selected item using repeater in flex 2.0 i'm using httpService to get rss feed and showing images in repeater control, i want to show message with selected(Clicked) image, but it not showing the title of selected image while selecting image.
