Mohammed,

You can use the visibleLayers property of the layer and the IdentifyParams.layerIds property to do this.

Mohammed,

The visibleLayers is only half of what you need to do... Next you will need to give the IdentifyParams the array of visible layers.

the below code ihave used for layer visibility but it is displaying only top active layer its not showing the raster layer information.
   <esri:visibleLayers>
    <s:ArrayCollection>
     <fx:Number>1</fx:Number>
     <fx:Number>2</fx:Number>
     
    </s:ArrayCollection>
   </esri:visibleLayers>

Mohammed,

You need to get in a habit of posting the code you are having issues with so that so much time is not spent going back and forth on tiny snippets of code that don't mean much if we can see how you are using that code.
