    <p>There are several problems in your code. But even if you solved them you wouldn't be able to parse the list of received stations with <code>DataContractJsonSerializer</code> out of the box.</p> <p><strong>Explanation:</strong></p> <p><a href="http://horaires-ter-sncf.naholyr.fr/?p=ws" rel="nofollow noreferrer">The web site offering the web service you are using</a> says a response from your first "JSON feed" looks like this:</p> <blockquote> <p>{"code":201,"success":{"gares":{"villefranche-d''alb.-ce":1750,"villefranche de rgue-12":1749,...}}}</p> </blockquote> <p>Have a look at the stations and their IDs:</p> <blockquote> <p>{"villefranche-d''alb.-ce":1750,"villefranche de rgue-12":1749,...}</p> </blockquote> <p>This is an associative array where the keys and values are not explicitly decorated with "Key" and "Value". But these decorations are necessary for <code>DataContractJsonSerializer</code> to parse the JSON. They would have to be in format </p> <blockquote> <p>[{“Key”:“villefranche-d''alb.-ce”,“Value”:“1750”},{“Key”:“villefranche de rgue-12”,“Value”:“1749”}]</p> </blockquote> <p>to be properly parsed by <code>DataContractJsonSerializer</code>. (The reason is that this serializer supports more complex types than <code>int</code> and <code>string</code> to be used as keys and values.)</p> <p><a href="http://theburningmonk.com/2011/05/json-serialization-datacontractjsonserializer-vs-javascriptserializer/" rel="nofollow noreferrer">This blog post</a> contains a very good description of the matter and how <code>JavaScriptSerializer</code> could be the solution. But unfortunately this class isn't available in Silverlight.</p> <p>More people having similar problems like you:</p> <ul> <li><a href="https://stackoverflow.com/questions/596271/deserialization-problem-with-datacontractjsonserializer">Deserialization problem with DataContractJsonSerializer</a></li> <li><a href="https://stackoverflow.com/questions/2826653/net-can-i-use-datacontractjsonserializer-to-serialize-to-a-json-associative-ar">.NET: Can I use DataContractJsonSerializer to serialize to a JSON associative array?</a></li> <li><a href="https://json.codeplex.com/discussions/258083" rel="nofollow noreferrer">https://json.codeplex.com/discussions/258083</a></li> <li><a href="https://connect.microsoft.com/VisualStudio/feedback/details/558686/" rel="nofollow noreferrer">https://connect.microsoft.com/VisualStudio/feedback/details/558686/</a></li> </ul> <p><strong>Solution:</strong></p> <p>Use <a href="https://json.codeplex.com/" rel="nofollow noreferrer">Json.NET</a>.</p>

    1. COI'm with you on that, a "manual" parse is needed. datacontract won't cut it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
