I do not understand what you are trying to do, but...
In your labelfunction logic, you are not using any values from the passed in row "item". That does not make any sense. The purpose of a labelFunction is to use the row item properties to build a string to display. Look at that logic again.

Hi Tracy Finally I would be able to retrieve labels but sorry I used labelFunction because for some reason labelfield is breaking other programmer's code: I have no idea why. So Below is my code. But Now I am doing some logical error. I am getting all the values in an array but it gives all the entries in all the whole list. For example if there are 10 values named friendly name I need the list to show Value 1 Value 2 Value 3 . . . . Value10 as 10 entries in the list but with my code it is showing Value1,Value2....Value10 10times in 10 rows with 10 entries in each row 10 times . I guess I am messing up in the logic. Can you please help me to fix this problem. Thanks alot for all your help Anuj /*************************CODE*********************************/ public var arrPoolNameText:Array=new Array(); private function assignFriendlyName(item:Object):String { var devicesTextFN:XMLList = devicesCollection.child("attributes").child("attribute"); for each (var attributesInFriendlyPool:* in devicesTextFN) { //Checks if the attribute name is pool if([EMAIL PROTECTED] == 'friendly-name') { var poolnameText:String = attributesInFriendlyPool.toString(); arrPoolNameText.push(poolnameText); } } return arrPoolNameText.toString(); } <mx:List id="nvrsInPoolList" labelFunction="assignFriendlyName" horizontalScrollPolicy="on" allowMultipleSelection="true" dragMoveEnabled="true" dragEnabled="true" dropEnabled="true" y="105" x="17" height="462" width="294"/> On Mon, Dec 1, 2008 at 6:36 PM, Tracy Spratt <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: Skip the Array entirely.

Then nvrsInPoolList.selectedItem will contain the entire xml node and you can access any value from it, Tracy ________________________________ From: [email protected] <mailto:[email protected]> [mailto:[email protected] <mailto:[email protected]> ] On Behalf Of anuj sharma Sent: Monday, December 01, 2008 4:27 PM To: [email protected] <mailto:[email protected]> Subject: Re: [flexcoders] Is there any Name -Value Pair concept for Arrays? Hi Tracy Yes I have attached code to tell you exactly how I am doing this. I am assigning an Array to my dataProvider and my array consists of XML Nodes. I hope I answer all of your questions. I am putting array of XML Nodes as dataProviders in List. I hope the code below will help you. Please let me know how to solve the problem of displaying different entities as labels and values in the List.

But whatever your display component, there is a way to specify which property on the item you want to display. You say your dataProvider is an "array". Are you sure? How are you sure? Are you using the work "array" in its purely technical sense, or in a more generic sense, that includes "associative array" and "arrayCollection"? If it is an Array, what is it an array of? (dynamic objects, scalar values, xml nodes?) What is your resultFormat? Have you inspected your data in the result handler function?

Hi All I am retrieving some data using HTTP from PostGres database. I would be successfully able to put all the entries in UDN's in the list box (using REST Calls). Now my requirement is that I need to display an attribute name Friendly name which is already in the database as the label (VISUAL entry ) in the list but when user performs different operations like drag and drop, I need the complete string in form XML to be send. So to make long story short I need to display friendly name as list entries but behind the curtain that label have exact complete value coming from the Database. Now is there any way that I can tell my data provider (which is an Array in my case) that to display just the specific attribute for the database and while doing operation send the whole value. Any links, examples and help will be appreciated. Thanks Anuj
