    <p>I need to pass some data between two action results so I thought I'd try <code>TempData</code> (I'm really new to MVC so bear with me). This is what I've tried:</p> <pre><code>public ActionResult Edit(Companies companies, HttpPostedFileBase file) { if (ModelState.IsValid) { try { if (file != null) { //Do stuff with file, save changes to database etc. TempData["Companies"] = companies; return RedirectToAction("bgcTest2", "Companies"); </code></pre> <p>Now the temp data is stored. And to retrieve it:</p> <pre><code>public ActionResult bgcTest2(string BolagsID, Companies companies) { try { companies = TempData["Companies"] as Companies; int test = companies.BolagsID; </code></pre> <p>Now here's the problem; <code>companies.BolagsID</code> has a value but <code>test</code> is always null. Why? And how do I fix it?</p> <p><strong>EDIT:</strong></p> <p>I've noticed a rather curious thing; when trying Darin Dimitrovs suggestion, and probably when doing my try aswell, if I put a breakpoint only on the line which returns the null value it doesn't break until the line after. As if that line is commented out and doesn't execute at all. Welcome to the Twilight Zone.</p> <p><strong>EDIT2:</strong></p> <p>Take 2:</p> <pre><code>[HttpPost] public ActionResult Edit(Companies companies, HttpPostedFileBase file) { if (ModelState.IsValid) { try { if (file != null) { // non related stuff return RedirectToAction("bgcTest2", "Companies", new {BolagsID = companies.BolagsID}); </code></pre> <p>And:</p> <pre><code>[Authorize] public ActionResult bgcTest2(int BolagsID) { try { int test = BolagsID; </code></pre> <p>I still get that "test does not exist in the current context".</p> <p><strong>EDIT3:</strong></p> <p>Take 2 works fine. My variables were <code>null</code> upon declaration because I never used them anywhere. I thought I'd take it one step at a time, but evidently, in some cases, you'll have to take a couple of steps to see it any of them works.</p> <p>Lesson learned: Be sure to use declared variables, otherwise they will be <code>null</code>.</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.
