Flex 3: DataGrid Column width on resize

That's expected behavior. With ScrollPolicy.OFF, the datagrid will shrink

down all column until they fit, then when you expand, they may expand

differently because they lost their proportions during the shrinking. You

may want to call your columns sizing code when the app resizes.

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" />
