Getting FeatureLayer from ArcGISDynamicMapServiceLayer

shashinanjaiah

I am trying to get the Featurelayer directly form the map to add an event for infopopup on mouseover. I went through the samples and it works when I create a new instance of the feature layer and add it to the map. It duplicates my layers on the map.

structureFeatureLayer = new FeatureLayer;
    structureFeatureLayer.url = "sampleUrl";
    structureFeatureLayer.mode = "snapshot";
    structureFeatureLayer.outFields = ['FIELD_ID'];
    structureFeatureLayer.addEventListener(GraphicEvent.GRAPHIC_ADD, sLayer_graphicAddHandler);
    map.addLayer(structureFeatureLayer);

//Event Listner when the map is initially loaded
   private function sLayer_graphicAddHandler(event:GraphicEvent):void
   {
    event.graphic.addEventListener(MouseEvent.MOUSE_OVER, onMouseOverStructure);
   }

Can I do this without creating a new instance of feature layer without adding to the map but add an event listener to the existing Map feature layer.

Any help would be appreciated.
Thanks

ibespalov,

I think I'm wishing for something that isn't possible.

Just a bit of Background:
I'm trying to replicate this below in SampleFlexViewer:
Sample feature layer based on mapserver layer

But since the mapservice Layer in question is already loaded/added to the map object, I'm trying to get away with not adding it again to the map as a feature layer.

At the moment I am adding it as a feature layer with null symbol style and null outline, so the user can't actually tell that it's been added twice.

When I tried your code above, the fLayer_graphicAddHandler event is never fired. I guess this can't be fired until features(graphics) are added to the map. and this can't happen if the featurelayer isn't added to the map.


I think I will end up using your code for something else I want to do though, so thanks.

Thanks

Andrew
