Legend Symbology

JuanSerratosa_López — Fri, 25 May 2012 11:18:38 GMT

Hi everyone,

I am an absolute beginner in this programing world, so I hope this question doesn´t sound stupid

Here is the thing, I have a map with a pie charts symbology applied, published in server and declared as a feature layer in my Silverlight application. When I try to include a legend it doesn´t display the simbology the map has, but another completely different. If I publish it as a ArcGISDynamicMapServiceLayer I can see the symbology in my application but still can´t see it in the legend...

Does anyone know how to solve this problem??

Thank you very much and congrats to all of you that help others in this forum....

This may be because REST API does not support that type of symbology. Here's a list of supported symbols: http://sampleserver3.arcgisonline.com/ArcGIS/SDK/REST/symbol.html.

Legend control will display symbols from the layer renderer, which is also limited to REST API supported symbols. The reason why ArcGISDynamicMapServiceLayer does not have a problem showing these symbols is because what you get is actually an image. You can run Fiddler, to see that the result of export request is an image.

Thanks!!

Sorry for the delay in the answer...
You are right, I think it´s a not supported symbology by REST API... when I have time I´ll try rendering the symbology and see what happens...

Thank you again!!
