    <p>I think you should verify <code>routes.MapRoute</code> which you added to the route table. Do you really use <code>IdMaster</code> parameter or you should rename it to <code>Id</code>? It can be that you just forget to add the custom rule.</p> <p>Another problem which I could see is the syntax error: you use </p> <pre><code>.navGrid(pager, {... </code></pre> <p>instead of</p> <pre><code>.navGrid('#pager', {... </code></pre> <p>(the variable <code>pager</code> in undefined).</p> <p>Another possible problem is possible id duplicates. Be sure that ids of the detail grid has <em>another values</em> as the ids from the master grid. Because ids are strings you can for example use prefixes for the ids: like <code>'m_'+ch.Id</code> for the master grid and <code>'d_'+bah.Id</code> for details grid.</p> <p>Some more remarks:</p> <ul> <li><code>sidx</code> and <code>sord</code> should not be included in the JSON response of the server. Instead of that <code>total</code> should be included. See <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:retrieving_data#json_data" rel="nofollow noreferrer">here</a> for more information.</li> <li>I recommend you to use <code>datatype: "local"</code> instead of <code>datatype: "json"</code> for the details grid definition. It will prevent attempt to load data at the grid initialization.</li> <li>I recommend you to use <code>pager: '#pager'</code> instead of <code>pager: jQuery('#pager')</code>.</li> <li>I recommend you to use <code>key: true</code> in the <code>'Id'</code> column. In the case you will don't need to send <code>Id</code> values twice. If you would use additionally <code>jsonReader: {cell:''}</code> you can remove <code>cell</code> property like <code>id</code> property from the <code>rows</code> data. So you can use about the following <code>from ch in ms select new { new string[] { ch.Id.ToString(), ch.Descripcion }}).ToList()</code>. See <a href="https://stackoverflow.com/questions/3054463/jqgrid-3-7-does-not-show-rows-in-internet-explorer/3061669#3061669">here</a> or <a href="https://stackoverflow.com/questions/5764709/jqgrid-not-loading-data/5766189#5766189">here</a> for example.</li> <li>I recommend you to use error handling on the jqGrid at the beginning of your code. See the UPDATED part of <a href="https://stackoverflow.com/questions/5500805/asp-net-mvc-2-0-implementation-of-searching-in-jqgrid/5501644#5501644">the answer</a> with <a href="http://www.ok-soft-gmbh.com/jqGrid/jqGridDemoVS2010.zip" rel="nofollow noreferrer">the demo project</a>. Displaying of error messages can save many time of your debugging. The demo could be interesting for you as a ASP.NET MVC code example which use jqGrid.</li> </ul>

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.
