Question

i want to set fade effect to the GridRow when i remove it using removeChld() function

please tell me the solution ...

Answer 1

You can't use a Fade effect on a DataGridColumn instance because it has no "alpha" property (which is used by the Fade effect)

Answer 2

You can do this:

<?xml version="1.0" encoding="utf-8"?>
<mx:Grid xmlns:mx="http://www.adobe.com/2006/mxml"&gt;
    <mx:Script>
     <![CDATA[
      import flash.display.DisplayObject;

      import mx.containers.GridRow;
      import mx.effects.Effect;
      import mx.effects.Fade;
      import mx.events.EffectEvent;

      override public function removeChild(child:DisplayObject):DisplayObject {
       if(child is GridRow) {
        var fade:Fade = new Fade;
        fade.alphaFrom = 1;
        fade.alphaTo = 0;
        fade.addEventListener(EffectEvent.EFFECT_END, fadeEndHandler);
        fade.play([child]);
       } else {
        super.removeChild(child);
       }

       return child;
      }

      private function fadeEndHandler(e:EffectEvent):void {
       super.removeChild(GridRow(e.effectInstance.target));
      }

     ]]>
    </mx:Script>
</mx:Grid>

Make this a new MXML component, like FadingGrid, and use as normal. However, now removeChildAt is not overridden and thus using it won't produce the fade effect.
