Have you tried using Fiddler with your app? This blog post might help you get started: http://blogs.esri.com/Dev/blogs/silverlightwpf/archive/2009/08/24/Troubleshooting-blank-layers.aspx. It is similar concept, you will be able to see the web requests and response. You can look at the Inspectors > WebForms to see what got sent to the server and try to repro by going directly to the REST endpoint.
thank u for your reply .. i try fiddler and read the article in your post , but No Error appear in URL request any other suggestion .. 🙂
Note: My Map in Dynamic and Map in online Example is Tiles and Accumulate Attribute Names: it is Empty and Use Hierarchy: false in my NW service but in online Example they are not Empty or false ..
