The deserializer has no knowledge of any type that maps to this name. Consider using a DataContractResolver or add the type corresponding to 'CustomerOrder' to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding it to the list of known types passed to DataContractSerializer. </code></pre> <p>Please help me resolve this error and deserialize JsonString</p>

    1. COHave you considered using `System.Web.Script.Serialization.JavaScriptSerializer` instead? It's easier to use IMO. The same applies for the Json.NET library: http://json.codeplex.com/

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.
