Adding Popups to a feature layer

Question

Hi, 
I have this layer: http://rmgsc.cr.usgs.gov/ArcGIS/rest/services/nhss_haz/MapServer/0/

I'm trying to configure the event of Mouse Over or Click on the feature to show the popup window.
I get nothing..

I think the service is not providing me the information I need for this, but everything else show up ok.

I'm adding the layer in code: 
- create a feature layer
- set the url 
- set the renderer
- add the layer to the map.

I'm missing something?
Can I add/create the "popup window" on my code based on attributes?

Thanks,

Another way is to set GraphicsLayer.MapTip. FeatureLayer inherits from GraphicsLayer. In this code, we are requesting for all fields and displaying the key-value pair (all attributes). This is triggered on mouse enter. Hovering a feature on your layer displays the maptip. You update the look and feel of your MapTip by adding border as in this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerMapTips. So your options are: InfoWindow, Toolkit.MapTip, or GraphicsLayer.MapTip.

You can also try MapTips like in this sample. This sample works fine for me, because all my feature layers are loaded at run-time (code-behind). You would need to setup the XAML as follows (change the "{Binding [STANAME]}" to any of your columns):

Then, in code-behind (at page load) you assign the feature service to the "MyMapTip" control as follows: public MainPage() { InitializeComponent(); FeatureLayer fl = MyMap.Layers["MyMapTipsLayer"] as FeatureLayer; fl.Url = "http://rmgsc.cr.usgs.gov/ArcGIS/rest/services/nhss_haz/MapServer/0/"; MyMapTip.GraphicsLayer = fl; } Note: Make sure you reference the Systems.Windows.Data.DLL; otherwise, you will get all sort of parse errors. That is! You are done! Hope this helps Hugo.

A feature layer has no default popup window automatically set.

Please look at this sample that demonstrates how to set an info window for a feature layer.
