Why is Silverlight Ignoring my Feature Symbol

Question

My application worked perfectly a few months ago.  Since then the client has upgraded to the latest version of ArcGIS Server (10.something, I believe).

Now, all of a sudden, the map ignores my Feature Symbols and uses instead the symbology associated with the map in Arc, presumably as specified by the REST service.

That would be fine, except I have some cool mouse-over animations that are now being ignored.

Anyone else encounter this?

Thanks.

Thank You for this feedback.
I have solved this problem of wanting to display pushpin and default symbology on
query results as well as preserving the ability to check/uncheck layer visibility
on a layer that may have query results.

Is there a difference between setting where clause on featurelayer vs running a querytask...

'Globally' one can say that a FeatureLayer is a GraphicsLayer running for you the query task.
But if you look at the details, a featurelayer is much more than that. It adds:
- default symbology
- time extent
- editing capabilities with save option
- querymode (ondemand, selectiononly)
- attribution
   
Now, my client would like me to NOT show (all) features, just the query results (using the default msd renderer)...

In your case, to display a query result with the default symbology, you might use a feature layer in selectinonly mode ant put the graphics coming from your query in this layer in order to take advantage of the automatic symbology (in short, replace your graphicslayer with pushpin symbology by a featurelayer in selectionlonly mode)

Hi Dominique...

Is there a difference between setting where clause on featurelayer vs running a  querytask...
I think I am a bit stumped. My current querytask returns results that I build in MyGraphicsLayer as RedPushPins.
I have a ArcGISDynamicMapLayer for the layers in this map, plus N feature layers for my OnDemand MapTips; So when user queries, I set visibility of these two items to true, and draw the push pin.
Now, my client would like me to NOT show (all) features, just the query results (using the default msd renderer)...

what is the right way to do this?
