    <p>I am having a strange caching problem and I believe it might be related to the fact that I am using a Entity Data Model as my data source.</p> <p>The problem is that I can update the database directly and it doesn't reflect on the actual site until I republish the project. The data does display properly when viewing the project locally.</p> <p>The odd part is that it is only incorrect on the front end. If I view the record via the CMS, it shows properly.</p> <p>Some source code:</p> <pre><code>// *** CMS CONTROLLER *** [HandleError] public class SiteManagerController : Controller { static DataModel DB = new DataModel(); // via CMS Controller // CMS - Get the data *** PULLS DATA CORRECTLY public ActionResult Content() { List&lt;SiteContent&gt; viewData = DB.SiteContents.OrderBy(c =&gt; c.Title).ToList(); return View(viewData); } // via CMS Controller // CMS - Update logic [HttpPost] [ValidateInput(false)] public ActionResult ContentEdit(int ID, FormCollection formValues) { SiteContent siteContent = DB.SiteContents.Single(c =&gt; c.ID == ID); try { UpdateModel&lt;SiteContent&gt;(siteContent); DB.SaveChanges(); return RedirectToAction("Content"); } catch { throw; } } } // *** HOME CONTROLLER *** [HandleError] public class HomeController : Controller { static DataModel DB = new DataModel(); [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] public ActionResult Index(string strSlug) { data = DietCenterDB.SiteContents.Single(c =&gt; c.Slug == strSlug); return View(data); } } </code></pre> <p><strong>* UPDATE *</strong> It seems that there is some sort of timed delay associated with this issue. If I update the CMS/database everything functions properly after 15-20 minutes. Perhaps some object related to the front end data access needs to timeout or expire in order to grab the new content?</p> <p><strong>* UPDATE #2 *</strong> It seems that it's only the varchar/text fields that aren't updating properly. If I change an int field, it updates properly and the information is changed on every page.</p>

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.
