I have a jquery treeview which I grabbed from <a href="http://jquery.bassistance.de/treeview/demo/" rel="nofollow">http://jquery.bassistance.de/treeview/demo/</a> when the number of nodes and sub nodes were small I had no problem loading the tree, but as the content grows the loading is taking very long time almost to the point that using the treeview seems a bad idea. this is part of my view where I construct the treeview <pre><code><script type="text/javascript"> $(function () { $("#Ul1").treeview({ collapsed: true, prerendered: true }); }); </script> </code></pre> <pre><code><ul id="Ul1" class="treeview-black"> <% foreach (var t in (IEnumerable<itemSpecifications>)ViewData["items"]) {%> <li class="expandable"><%=Html.RouteLink(t.itemName, null, new { controller = "RQA", action = "itemaction", policyname = t.itemName})%> <%if (t.itemCount > 0) {%> <%for(int i=0;i<t.itemCount ;i++){%> <ul> <li class="expandable"><%=Html.RouteLink(t.subitems[i].Name, null, new { controller = "controller1", action = "itemUpdate", rule = t.subitems[i] })%></li> </ul> <%}%> <%}%> <% }%> </li> </ul> </code></pre> and the controller contains the code below: <pre><code>public ActionResult Index() { items1 = (from itemsInfo itemInfo in _itemInfoCollection where itemInfo.Name == "val1" select new itemSpecifications { itemName = itemInfo.Name, itemCount = GetItemscount(), subitems = GetSubItems() }); ViewData["items"] = items1 ; return View(); } </code></pre> sometimes the loading of the entire page takes so long that the page basicaly crashes (unable to load) and sometimes when the page loads successfully and I click on any of the plus signs next to the nodes it takes such a long time to open the subitems. it is worth to mention that the average subnodes are 400 items, any advise will be highly appreciated, I am using MVC3 and it is in IE Thanks

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.
