Rendering FeatureLayer based on pre-defined symbology?

Question

The sample at http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start.htm#FeatureLayerRendering shows how to add a FeatureLayer to the map.

This sample hard-codes the symbology - but is it possible to access the symbology (and other properties) which were defined in ArcMap, then published to ArcGIS Server?

Eg my services catalog shows a layer with properties like:

Min. Scale: 100000
Drawing Info: 
Renderer: Simple Renderer: 
Symbol: Picture Marker Symbol:

Can I use these programatically, without having to hard-code them?

Thanks,
Steve

Does it mean that the FeatureLayer will use the symbol it uses in ArcMap?

Yes, if the rest endpoint created by your published service contains a renderer, this will be picked up by the SL/WPF API.  For example: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/0 This FeatureLayer includes a Unique Value Renderer (see Drawing Info).

For more information on what is new to the ArcGIS 10 Rest API, you can visit this link:http://help.arcgis.com/EN/arcgisserver/10.0/apis/rest/index.html

Hi,

Where can i find the information for this ArcGIS 10 renderer?

Does it mean that the FeatureLayer will use the symbol it uses in ArcMap?

Oh you are right, the Renderer is new to ArcGIS 10.

Cool, I'll upgrade my VS and SL toolkit and try again using AGS 10.

thanks for the help,
Steve
