I've been thinking about a workaround for the problem, and I've found one. I inject an extra parameter into the querystring collection. That way I can put the search filter into the querystring. Normally the querystring collection is readonly, but I've found some code to fix this. Code to add parameter to querystring: <pre><code> public static void Add(string name, string value) { NameValueCollection qs = System.Web.HttpContext.Current.Request.QueryString; qs = (NameValueCollection)System.Web.HttpContext.Current.Request.GetType().GetField("_queryString", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(System.Web.HttpContext.Current.Request); PropertyInfo readOnlyInfo = qs.GetType().GetProperty("IsReadOnly", BindingFlags.NonPublic | BindingFlags.Instance); readOnlyInfo.SetValue(qs, false, null); qs[name] = value; readOnlyInfo.SetValue(qs, true, null); } </code></pre> New controller code: <pre><code> public ActionResult Index(string SearchFilter) { // check querystring search if (string.IsNullOrEmpty(SearchFilter) && !String.IsNullOrEmpty(Request.QueryString["search"])) SearchFilter = Request.QueryString["search"]; var model = new Models.SubscriptionListModel { SearchFilter = SearchFilter }; if (string.IsNullOrEmpty(SearchFilter)) { model.SubscriptionList = _subscriptionHandler.ReadWhereIdLessThanThousand(); } else { // add search filter to the querystring Common.QueryString.Add("search", SearchFilter); model.SubscriptionList = _subscriptionHandler.ReadWhereContains(SearchFilter); } if (Request.IsAjaxRequest()) { return View("SubscriptionList", model); } else { return View("Index", model); } } </code></pre> If anyone has a cleaner solution to fix this, suggestions are still welcome :-)

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.
