    data
    text
    <p>Background:</p> <ol> <li>I have a MVC2 project and am using jQuery 1.4.2.</li> <li>I have a .NET class that I put into a view using a JsonResult.</li> <li>The page then uses jQuery to do stuff which will result in properties of the object put on the page by item (2) above.</li> <li>When a certain page element is clicked jQuery $.post's the JSON.stringify(myObj) back to action method.</li> </ol> <p>What I'd like to be able to have is something like:</p> <p>[HttpPost] public ViewResult MyAction(MyClass minime) { }</p> <p>... MyClass would be the .NET class to deserialize the JSON into which should be fine given it was the type MyClass that got "return Json(MyClass);"</p> <p>At the present time what I'm seeing is that either the object parameter is null or has no values as set by the JS/jQuery code. If I try:</p> <p>MyClass foo = new MyClass(); UpdateModel(foo);</p> <p>It doesn't throw an exception but similar doesn't populate the class either.</p> <p>Anybody have any ideas on how to solve this? Or how to deal with JSON sent back to the action method and get it into a class.</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.

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