    <p>I have an ASP.NET MVC page that has left Menu Navigation that is built dynamically using JQuery Treeview Control.</p> <p>This Treeview has the list of <strong>ProductNames</strong> as the <strong>Parent Node</strong>(For Example: 10 Products). Each of these Products have a <strong>ChildNode</strong> as <strong>DocTypeName</strong>(For Example: 3 DocTypeNames).</p> <p>Here When the user clicks on ParentNode, it expands and shows DocTypeNames. When the User Clicks on DocTypeName, it loads the partialView by calling the controller ActionResult <strong>DocumentDetails</strong> through Ajaxy way.</p> <p>From the below code I am able to read the DocTypeName that is clicked. But I am not able to read the ProductName. It says "Undefined".</p> <p>Anyone has any idea how to pass the Parent ProductName to the controller?</p> <p><strong>NavigationProducts.ascx Page:</strong></p> <pre><code>&lt;%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl&lt;MedInfoDS.Controllers.ProductViewModel&gt;" %&gt; &lt;script type="text/javascript"&gt; $(document).ready(function () { $(".docId").click(function () { alert("DocTypeName: " + this.id); alert("ProductName: " + this.ProductName); //Error throwing here "Undefined" $("#docDetails").load('&lt;%= Url.Action("DocumentDetails") %&gt;', { ProductName: "darbepoetin alfa", DocTypeName: this.id }, function (responseText, status) { }); return false; }); }); </code></pre> <p> </p> <pre><code>&lt;div id="treecontrol"&gt; &lt;a title="Collapse the entire tree below" href="#"&gt;Collapse All&lt;/a&gt; | &lt;a title="Expand the entire tree below" href="#"&gt;Expand All&lt;/a&gt; | &lt;a title="Toggle the tree below, opening closed branches, closing open branches" href="#"&gt;Toggle All&lt;/a&gt; </code></pre> <p></p> <pre><code>&lt;div id="divByProduct"&gt; &lt;ul id="red" class="treeview-red"&gt; &lt;% foreach (var item in Model.Products) { %&gt; &lt;li&gt;&lt;span&gt; &lt;%=item.Name%&gt;&lt;/span&gt; &lt;ul&gt; &lt;%foreach (var item1 in Model.DocTypes) { %&gt; &lt;li&gt;&lt;span&gt; &lt;%= Html.ActionLink(item1.DocTypeName, "Products", new { ProductName = item.Name, DocTypeName = item1.DocTypeName })%&gt; &lt;br /&gt; &lt;a class="docId" href="#" id="&lt;%=item1.DocTypeName%&gt;"&gt;&lt;%= item1.DocTypeName%&gt;&lt;/a&gt; &lt;%= Html.Hidden("ProductName", item.Name)%&gt; &lt;/span&gt;&lt;/li&gt; &lt;% } %&gt; &lt;/ul&gt; &lt;/li&gt; &lt;% } %&gt; &lt;/ul&gt; </code></pre> <p></p> <p><strong>Controller Method:</strong></p> <pre><code>// Response to AJAXy call to populate details for given ProductName and DocType [HttpPost] public virtual ActionResult DocumentDetails(string ProductName, string DocTypeName) { var entities = new MIDSContainer(); if (ProductName == null) return View(); int ProductId = (entities.Products.FirstOrDefault(p =&gt; p.Name == ProductName)).ProductId; int DocTypeId = (entities.DocTypes.FirstOrDefault(d =&gt; d.DocTypeName == DocTypeName)).DocTypeId; var documents = (from d in entities.Documents.Where(p =&gt; p.ProductId == ProductId &amp;&amp; p.DocTypeId == DocTypeId &amp;&amp; p.AvailableForUse == true &amp;&amp; p.Status == "Approved") orderby (d.Description) select d).ToList(); return View(documents); } </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.

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