You might want to listen for the Failed event as well. Your request is probably failing.
If that's the case, first make sure the service works from the plain HTML REST interface. The look in Fiddler (www.fiddlertool.com) and try and understand what requests and responses (or lack of) that there are. Did any fail? Did the request parameters look ok? What did the server respond? etc.
Hi Morten ,
I installed fiddlertool . I am getting below error .
{"error":{"code":500,"message":"Error Submitting Job","details":[]}}
It sounds like you a trying to access a job that hasn't been created.
Did you call SubmitJob first? Is your GP tool even asynchronous? (if not you should execute the tool and not submit it)
That really depends on how you configured your service and what it expects (look at the previous page that describes the service metadata for specific details on the parameters). Next click the "Help" link in the upper right to read about the expected syntax.
Make sure that when you execute your GP tool from Silverlight, that the parameters you provided is of the same type as the Input parameters specify in the mentioned metadata.
