    <p>I am using ASP.NET MVC 1.0. I have an ActionResult which receives a form post with a value from a drop down list. It then redirects to an ActionResult, passing the value as a parameter. Here are my 2 ActionResult methods:</p> <pre><code>[AcceptVerbs(HttpVerbs.Post)] public ActionResult FindPromo() { var promoId = Convert.ToInt32(Request.Form["ddlPromotion"]); return RedirectToAction("GetPromo", new { id= promoId }); } public ActionResult GetPromo(int id) { if (promoId &gt; 0) { var model = GetModel(id); if (model.Promo != null) { return View("Promo", GetModel(id)); } } return RedirectToAction("NotFound"); } </code></pre> <p>When I debug this, the value from the drop down list is pulled correctly from my form, but on the redirect, a different value from a previous request comes through as the promoId value on the GetPromo method. This happens even if I I totally close out of the page and reload it, almost as if it's cached somewhere. I know this is something simple, but I've never run across this before.</p> <p>EDIT:</p> <p>I changed the parameter names from promoId to id, and also updated my routing table. I've updated my code sample above, and here are my routes:</p> <pre><code> routes.MapRoute("GetPromo", "{controller}/GetPromo/{id}", new { controller = "Promo", action = "GetPromo" }); routes.MapRoute("FindPromo", "{controller}/FindPromo/{id}", new { controller = "Promo", action = "FindPromo" }); </code></pre> <p>I'm still getting the same results with the parameters, however.</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.
