Flex datagrid automatic width?

Question

Hello,
I'm currently attempting to use the datagrid component to
display some information. This information will be pulled in
externally, and I will not know the length of the content that will
be in each row. Is there a way that I can get the width of the
datagrid to automatically be the width of the row that has the most
content? For example, if my data grid displays:
this is row one
this is row two
this is row three... is has the most content....
I would like the datagrid to be the width of row three
(without scrollbars). I can't specifiy a width because I don't know
how long the content will be, and specifying a width of 100% makes
the datagrid wider than it needs to be. Any ideas?
Thanks in advance for any advice.

Hi Srilatha,
DataGrid width is 100% and the main application width also 100%, So the
DataGrid will try to occupy the whole window, when you do "restore down" &
"maximize" Application width will change.. and it will effect DataGrid and
its columns also. Try to give some fixed width for dataGrid and you can
expect the result.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
height="100%" width="100%">
    <mx:Script>
        <![CDATA[
            import mx.core.ScrollPolicy;
            private var isVisible:Boolean = true;
            private function creationCompleteHandler():void
                dataGrid.horizontalScrollPolicy = ScrollPolicy.ON;
                artist.width = dataGrid.width * 0.40;
                album.width = dataGrid.width * 0.50;
                Price.width = dataGrid.width * 0.10;
                dataGrid.horizontalScrollPolicy = ScrollPolicy.OFF;
        ]]>
    </mx:Script>
    <mx:DataGrid id="dataGrid" width="500" height="100%"
creationComplete="creationCompleteHandler()">
        <mx:ArrayCollection>
            <mx:Object Artist="Pavement" Price="11.99"
                       Album="Slanted and Enchanted" />
            <mx:Object Artist="Pavement"
                       Album="Brighten the Corners" Price="11.99" />
        </mx:ArrayCollection>
        <mx:columns>
            <mx:DataGridColumn id="artist" dataField="Artist"/>
            <mx:DataGridColumn id="album" dataField="Album"
visible=""/>
            <mx:DataGridColumn id="Price" dataField="Price" />
        </mx:columns>
    </mx:DataGrid>
</mx:Application>
