    <p>Following is my code with the business logic. I get below json by calling the webservice and and I deserialized that to the object (as shown in my Entity). Now, I want to display Dropdown with the category selections and once the user select the category it should display checkbox lists of subcategories.</p> <p>As per my below code the dropdown should have "Eat" &amp; "Entertainment" options. And if the user select "Entertainment" then it should display "All", "Movie, &amp; "Bowling" as the checkbox list. Can anyone please help me how to have this in MVC3 &amp; C#?</p> <p>JSON:</p> <pre><code> { "Code":0, "Status":"Done", "Categories":[ { "ID":1, "Name":"Eat", "Subcategories":[ {"Flag":false,"ID":100,"Name":"Food"}, {"Flag":false,"ID":101,"Name":"Fast Food"}, {"Flag":false,"ID":102,"Name":"Other"} ] }, { "ID":2, "Name":"Entertainment", "Subcategories":[ {"Flag":false,"ID":100,"Name":"All"}, {"Flag":false,"ID":101,"Name":"Movie"}, {"Flag":false,"ID":102,"Name":"Bowling"} ] }, } ] } </code></pre> <p>Entity:</p> <pre><code> public class MyData { public int Code { get; set; } public string Status { get; set; } public List&lt;Category&gt; Categories { get; set; } } public class Category { public string Name { get; set; } public int ID { get; set; } public List&lt;Subcategory&gt; Subcategories { get; set; } } public class Subcategory { public string Name { get; set; } public int ID { get; set; } public bool Flag { get; set; } } </code></pre> <p>ServiceCall:</p> <pre><code> public MyData GetAllCategories() { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://host/data/categories/"); request.ContentType = "application/json; charset=utf-8"; request.Method = "GET"; string returnJson = string.Empty; using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream)) { while (!reader.EndOfStream) { returnJson += reader.ReadLine(); } } } } MyData deserializedMyData = JsonConvert.DeserializeObject&lt;MyData&gt;returnJson return deserializedMyData; } </code></pre>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
