It depends on what you mean by flickering.  It would be unusual for a label to 
flicker.  Images often do, and SuperImage from quietlyscheming.com can help, 
but if the label if flickering, something else might be the issue.

Subject: [flexcoders] Flickering in datagrid Header Renderer while loading data


I m also facing similar issue,Please see my code below:-

Custom Header Renderer:

[Bindable]
private var theImage:Class;
override public function set data(value:Object):void
{
dgColumn = value as DataGridColumn;
if(dgColumn.sortDescending)
this.theImage = this.downArrow;
else
this.theImage = this.upArrow;
}

]]>
</mx:Script>

<mx:Image source="{this.theImage}"/>


Image is flicking when data loads in data grid. I also tried Label with some 
text, that to is flicking.
Everything looks good as soon as data loading is over .Is there any ways to 
avoid this flicker ??

Please throw some light in to it

Regards,
Dharmendra
