    <p>I am using Json.NET to create a definition of json whose structure may change. I am therefore unable to simply serialize a class and am creating the structure on the fly using Json to Linq. I am having issues creating the following structure using JObject, JArray, JProperty, etc</p> <pre><code> { 'external_id':'UNIQUE_ID_222222222', 'firstname':'John', 'lastname':'Smith', 'customFields': { 'custom1':'custom1 val', 'custom2':'custom2 val', 'custom3"':'custom3 val' } } </code></pre> <p>I tried using the following code:</p> <pre><code>Dim json As New JArray() Dim jsonObj As New JObject( _ New JProperty("external_id", "UNIQUE_ID_222222222"), New JProperty("firstname", "John"), New JProperty("lastname", "Smith")) Dim jsonCustomFields As New JArray Dim jsonCustomObject As New JObject jsonCustomFields.Add(jsonCustomObject) For Each field In CustomFieldList jsonCustomObject.Add(New JProperty(field.Label, field.Value)) Next jsonObj.Add(New JProperty("customFields", jsonCustomFields)) json.Add(jsonContrib) </code></pre> <p>However when I do this I get a different pattern that was not accepted by the webservice</p> <pre><code>{[ { "external_id": "50702", "firstname": "John", "lastname": "Smithson", "customFields": [ { "custom1":"custom1 val", "custom2":"custom2 val", "custom3":"custom3 val" } ] } ]} </code></pre> <p>I thought that I should be adding properties directly to the JArray but doing this causes a run time exception.</p> <p>I have seen a similar pattern that is created when you deserialize a Dictionary(String, String) object but I don't really want to add my custom fields to a dictionary only to then deserialize them. It must be possible to create them using the above notation.</p>

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.
