You just have to override the createItemEditor method, such as:

override public function createItemEditor(colIndex:int, rowIndex:int):void
{
  super.createItemEditor(colIndex, rowIndex);
  itemEditorInstance.cacheAsBitmap = true;
  itemEditorInstance.opaqueBackground = 0xFFFFFF;
  itemEditorInstance.alpha = 1;
}
