Cursor Hover Style Over DynamicMapService

Question

I want the cursor style to change from the default to a pointer when the user hovers over features drawn in an ArcGISDynamicMapServiceLayer.  Currenty I'm accomplishing that by using a transparent FeatureLayer with the same extent as the DynamicMapServiceLayer.  I use the onMouseOver and onMouseOut events of the FeatureLayer to change the MapCursor property of the map appropriately.  Is there a better way to do that?  Thanks in advance.

But why duplicate things by showing both feature and dynamic layers - why not remove the dynamic layer and just use the feature?

Stephen - Looks like the "why not" may be a matter of performance.  I tried using a feature layer alone, while maintaining the same symbology, and the draw time suffers.  The feature layer has yet to draw at all in IE9.

The draw time is better in Chrome and Firefox, but still slow.  Am I doing something wrong?  Thanks.

Derek - I was using IE9 zoomed in to level 14 and closer.  Sometimes I'd click and the infoWindow would popup.  Sometimes I'd click a few times and not get anything.  I can't consistently reproduce the problem though.  Maybe you are right and there isn't one.  Thanks for the tip about feature layer generalization.  I didn't know that.

Stephen - That is a good question.  The short answer is because I did not know how to create the same cartographic effect with a feature layer.  But if that is the way to go, then I'll take another look.  Thanks for the advice.

Looking at your site, I think the method you're using works well

+1, it looks great.
