    <p><code>Request.InputStream</code> allows you to access the raw request data. If this data is formatted using some standard format such as <code>application/x-www-form-urlencoded</code> or <code>multipart/form-data</code> or some other format that the default model binder understands you do not need to use <code>Request.InputStream</code>. ASP.NET will parse the request values and you will be able to access them directly using <code>Request[...]</code>. Of course in ASP.NET MVC you don't even need to use <code>Request[...]</code> because you can define a view model which your controller action will take as parameter and leave the model binder assign its properties from the request.</p> <p>There are cases though when you might want to access the raw request stream. For example you have invented some custom protocol and the client sends some custom formatted data in the request stream. Those cases are very rare since inventing custom protocols is not very common.</p> <p>Now back to your question. In your case you could define a view model:</p> <pre><code>public class MyViewModel { public string SomeData { get; set; } } </code></pre> <p>which your controller action will take as argument:</p> <pre><code>public ActionResult GetSomeData(MyViewModel model) { // model.SomeData will contain the Hello string that the client sent return Json("something"); } </code></pre> <p>and on the client I would recommend you using the <code>JSON.stringify</code> method which is natively built into modern browsers to JSON serialize the request javascript literal into a JSON string instead of manually writing the JSON as you did:</p> <pre><code>$.ajax({ type: 'POST', url: 'Home/GetSomeData', data: JSON.stringify({ someData: 'Hello' }), contentType: 'application/json; charset=utf-8', success: function (msg) { alert(msg); // Insert the returned HTML into the &lt;div&gt;. $('#dvResult').html(msg); } }); </code></pre>

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.
