    <p>Without routing, <code>HttpContext.Current.Session</code> is there so I know that the <code>StateServer</code> is working. When I route my requests, <code>HttpContext.Current.Session</code> is <code>null</code> in the routed page. I am using .NET 3.5 sp1 on IIS 7.0, without the MVC previews. It appears that <code>AcquireRequestState</code> is never fired when using the routes and so the session variable isn't instantiated/filled.</p> <p>When I try to access the Session variables, I get this error:</p> <p><code>base {System.Runtime.InteropServices.ExternalException} = {"Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the &lt;configuration&gt;.</code></p> <p>While debugging, I also get the error that the <code>HttpContext.Current.Session</code> is not accessible in that context.</p> <p>--</p> <p>My <code>web.config</code> looks like this:</p> <pre><code>&lt;configuration&gt; ... &lt;system.web&gt; &lt;pages enableSessionState="true"&gt; &lt;controls&gt; ... &lt;/controls&gt; &lt;/pages&gt; ... &lt;/system.web&gt; &lt;sessionState cookieless="AutoDetect" mode="StateServer" timeout="22" /&gt; ... &lt;/configuration&gt; </code></pre> <p>Here's the IRouteHandler implementation:</p> <pre><code>public class WebPageRouteHandler : IRouteHandler, IRequiresSessionState { public string m_VirtualPath { get; private set; } public bool m_CheckPhysicalUrlAccess { get; set; } public WebPageRouteHandler(string virtualPath) : this(virtualPath, false) { } public WebPageRouteHandler(string virtualPath, bool checkPhysicalUrlAccess) { m_VirtualPath = virtualPath; m_CheckPhysicalUrlAccess = checkPhysicalUrlAccess; } public IHttpHandler GetHttpHandler(RequestContext requestContext) { if (m_CheckPhysicalUrlAccess &amp;&amp; !UrlAuthorizationModule.CheckUrlAccessForPrincipal( m_VirtualPath, requestContext.HttpContext.User, requestContext.HttpContext.Request.HttpMethod)) { throw new SecurityException(); } string var = String.Empty; foreach (var value in requestContext.RouteData.Values) { requestContext.HttpContext.Items[value.Key] = value.Value; } Page page = BuildManager.CreateInstanceFromVirtualPath( m_VirtualPath, typeof(Page)) as Page;// IHttpHandler; if (page != null) { return page; } return page; } } </code></pre> <p>I've also tried to put <code>EnableSessionState="True"</code> on the top of the aspx pages but still, nothing.</p> <p>Any insights? Should I write another <code>HttpRequestHandler</code> that implements <code>IRequiresSessionState</code>?</p> <p>Thanks.</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.
