    <p>I have an MVC application that when a link is clicked a page needs to be displayed based on the same values on another page. I can't figure out why what's getting passed is null instead of the string. My code is below.</p> <p>Controller:</p> <pre><code>public string searchQ { get { return (string)Session["searchQ"]; } set { Session["searchQ"] = value; } } public ActionResult Index() { Session["InitialLoad"] = "Yes"; return View(); } [HttpPost] public ActionResult Index(string heatSearch) { ViewBag.SearchKey = heatSearch; searchQ = heatSearch; return View(); } public ActionResult Index_Perm() { ViewBag.SearchKey = searchQ; return View(); } public ActionResult PartialMainLim(string heatSearch) { HomeModel C = new HomeModel(); ChemViewModel D = new ChemViewModel(); D = C.QueryResults(heatSearch); return PartialView(D); } public ActionResult PartialMain(string heatSearch) { HomeModel C = new HomeModel(); ChemViewModel D = new ChemViewModel(); D = C.QueryResults(heatSearch); return PartialView(D); } </code></pre> <p>The code in the index view looks like this (this one works):</p> <pre><code>@if (ViewBag.SearchKey != null) { &lt;div&gt; @Html.Action("PartialMainLim", "Home", (string)ViewBag.SearchKey) &lt;/div&gt; } </code></pre> <p>And in the index_perm view:</p> <pre><code>@if(ViewBag.SearchKey != null) { &lt;div&gt; @Html.Action("PartialMain", "Home", (string)ViewBag.SearchKey) &lt;/div&gt; } </code></pre> <p>When I check the value of SearchKey in both views it is correct. However for the method "PartialMain" null gets passed instead of the string, despite SearchKey being correct. This all works for the other view though. What am I doing wrong?</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.

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