    <p>I am using MVC3, Jquery, and jstree, my goal is to display the jstree with the help of json_data from the controller, I have researched this as much as I could but have not solved it, my problem is how to relate the function(n/node) to the action in the controller, and how to send the node list that I create in the controller action back to the view and parse the data, I will greatly appreciate any help or advise.</p> <pre><code> &lt;script type="text/javascript"&gt; $(function () { $("#demo1").jstree({ "themes": { "theme": "default", "dots": true, "icons": false, "url": "/content/themes/default/style.css" }, "json_data": { "ajax": { "async": true, "url": "/Home/GetItems", "type": "POST", "data": function (n) { return { id: n.attr ? n.attr("id") : 0 } "dataType": "text json", "contentType": "application/json charset=utf-8", "progressive_render": true } } }, "plugins": ["themes", "json_data", "dnd"] }) }); </code></pre> <p>and here is my controller code with the GetItems():</p> <pre><code> [AcceptVerbs(HttpVerbs.Post)] public JsonResult GetItems() { int cnt = 0; var itemRawData = (from ItemInfo itemtInfo in _itemInfoCollection where itemInfo.Name == "val1" || itemInfo.Name == "val2" select new itemSpecifications { itemName = itemInfo.Name, itemVersion = itemInfo.MajorRevision.ToString() + "." + itemInfo.MinorRevision.ToString(), iCount = ItemInfo.Count, ilist = itemInfo.Values.Cast&lt;subitem&gt;().ToList(), index = cnt++ }); TreeNode node = new TreeNode(); List&lt;TreeNode&gt; nodelist = new List&lt;TreeNode&gt;(); foreach (var t in itemRawData) { nodelist.Add(new TreeNode { data = String.Format("{0} {1} ({2})",t.itemName, t.itemVersion, t.iCount.ToString()), state = "closed", children = t.ilist }); } return Json(nodelist); } </code></pre> <p>any example or advise will be greatly appreciated!</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.
