Hi, Sherif,
Thanks for ur info. That saved my ass.
I made a class MyHeaderBackgroundSkin extending
DataGridHeaderBackgroundSkin and overrided its updateDisplayList
method not to do anything. ( not to draw its background )
And finally set the MyHeaderBackgroundSkin class to AdvancedDataGrid's
headerBackgroundSkin property as follows.
<mx:AdvancedDataGrid ... headerBackgroundSkin="{MyHeaderBackgroundSkin}">
Just in case for others having the same question, my codes are here.
[jp/ba77/MyHeaderBackgroundSkin.as]-----------------------------------------------------
package jp.ba77
{
import mx.skins.halo.DataGridHeaderBackgroundSkin;
public class MyHeaderBackgroundSkin extends DataGridHeaderBackgroundSkin
{
public function MyHeaderBackgroundSkin()
{
super();
}
override protected function
updateDisplayList(w:Number,h:Number):void{
// do nothing.
}
}
}
