Dynamic creation of radio buttons in a radio group, using a custom object?

Posted on 2009-04-09

I'm looking for information on how to create a radio button group, based on the contents of an list of objects.
These objects, of type "Answer" have 2 string properties of "answerLetter" and "answerValue".

What I want to do is iterate over this collection of Answer objects, and create a radio button group, with the label being the Answer Value and the data being the Answer Letter.

How would I do this?  It appears to be adding the contents of my array collection as new radio buttons, but they are all on top of each other.  How do I space them out?  The text values appear to be populating correctly, but there appears to be n number of buttons on top of each other...
Simple answer class...

public class Answer


	private var _answerText:String;

	private var _answerLetter:String;


	public function Answer(...args)


  		this._answerLetter = args[0];

    		this._answerText = args[1];     		



        public function get answerText():String{

            return _answerText;



        public function set answerText(answerText:String):void{

            _answerText = answerText;



        public function get answerLetter():String{

            return _answerLetter;



        public function set answerLetter(answerLetter:String):void{

            _answerLetter = answerLetter;



The panel has this on it.

<mx:RadioButtonGroup id="answerGroup" />

        <mx:Repeater id="rep" dataProvider="{cbCol}">

                <mx:RadioButton group="{answerGroup}" id="radios" label="{rep.currentItem.answerText}" data="{rep.currentItem.answerLetter}" />


cbCol is populate when this method is called.

public function CreateRadioButtons(answersForThisQuestion:ArrayCollection){


	cbCol = new ArrayCollection();

	for(var i:int = 0; i<answersForThisQuestion.length; i++){		  cbCol.addItem(answersForThisQuestion.getItemAt(i) as Answer);

Put the RadioButtonGroup in a Tile component.
<mx:Tile direction="horizontal">

<mx:RadioButtonGroup id="answerGroup" />

        <mx:Repeater id="rep" dataProvider="{answersForThisQuestion}">

                <mx:RadioButton group="{answerGroup}" id="radios" label="{rep.currentItem.answerText}" data="{rep.currentItem.answerLetter}" />
