Even the DataGridColunm has property headerRenderer.I tried the following ..But its not working ..plzz help me out
<mx:DataGridColumn id="timeCol"    dataField="Time"    headerText="Time (ms):"  headerRenderer="Display" />
The code for Display.mxml is as follows
<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="http://www.adobe.com/2006/mxml" initialize="inti()">
    <mx:Script>
        <![CDATA[
            public function inti():void{
                this.addEventListener(MouseEvent.DOUBLE_CLICK,edit);
            public function edit():void{
                trace("In Naga");
                this.text="naga";
        ]]>
    </mx:Script>
</mx:Label>
