try this, my old code,
<mx:DataGrid id="dg3" width="100%" dataProvider="{orgXML.location}"
creationComplete="dg3.columns =
generateCols(orgXML.location, false)" rowHeight="20"
click="selectStore(event)" updateComplete="d3build()"
allowMultipleSelection="true" variableRowHeight="true" />
private function generateCols(input:XMLList, useAttributes:Boolean =
false):Array
{
var e1:XML = input[0];
var columns:Array = [];
var children:XMLList ;
if (useAttributes)
{
children = e1.attributes();
}
else
{
children = e1.children();
}
for each(var child:XML in children)
{
var col:DataGridColumn = new DataGridColumn();
col.dataField = useAttributes ? "@" + child.name() : child.name();
var fieldName:String = child.name();
col.headerText = fieldName.charAt(0).toUpperCase() +
fieldName.substr(1);
// create itemrenderer
if(col.headerText == "Survey")
col.itemRenderer = new ClassFactory(imageCR);
else if (col.headerText == "Percent" )
col.itemRenderer = new ClassFactory(percentCR);
var tempObj:Object = new Object();
tempObj = {
label : col.headerText
}
cList.addItem(tempObj);
columns.push(col);
}
return columns;
}
