    <p>I am using ASP.MVC 1 to return an IEnumerable of objects (say, Cars):</p> <pre><code>public class Car : Entity&lt;Car&gt; { public virtual string Make { get; set; } public virtual double Length { get; set; } public virtual string Colour { get; set; } } </code></pre> <p>like this:</p> <pre><code>[AcceptVerbs(HttpVerbs.Post)] public JsonResult GetRoutes() { IEnumerable&lt;Car&gt; cars = _carTask.GetCars(); return Json(cars); } </code></pre> <p>In my page, I want to iterate over each car returned, so I have this:</p> <pre><code>$.post("/Home/GetCars", null, function(cars) { alert("type of object returned is " + typeof cars + ", content is " + cars); $.each(routes, function() { alert(this); }); } ); </code></pre> <p>When I run this, the first alert box says: </p> <p>type of object is string, content is [{"Make":"BMW"}, {"Make":"Ford"}]</p> <p>Which tells me I am getting a string back (shouldn't i get an object back?), containing a Json structure with 2 objects. However the jquery $.each function then proceeds to iterate over each char in the string, so I get 46 alert boxes: the first says '[', then '{', then '"', then 'M', then 'a', then 'k'... you get the idea.</p> <p>From what I have read, jQuery should be parsing this as a collection, and should iterate only twice to show me to alerts, one for each car. I could then do alert(car.Make) to display the makes, but if I try that I get undefined (because a string doesnt have a Make property).</p> <p>What am I doing wrong? Thanks for any help, there must be an obvious error but i promise I have done plenty of googling first and came up with nothing! :)</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.
