    <p>I have created a sample signalR for POC. I want to call a hub method from Global.asax and pass a string value to client. My Message hub is :-</p> <pre><code>[HubName("messageHub")] public class MessageHub : Hub { public static IHubContext context = GlobalHost.ConnectionManager.GetHubContext&lt;MessageHub&gt;(); public void Message() { /* * services and updates the messages * property on the PushMessage hub */ //IHubContext context = GlobalHost.ConnectionManager.GetHubContext&lt;SignalR_Error_Logging.Models.ErrorModel&gt;(); List&lt;GenerateError.Repository.ErrorModel&gt; model = ErrorRepository.GetError(); context.Clients.pushMessages(model[0].ErrorMessage); } </code></pre> <p>I have defined two of the scripts in layout.cshtml</p> <pre><code>&lt;script type="text/javascript" src="../../Scripts/jquery-1.6.4.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="../../Scripts/jquery.signalR-0.5.3.js"&gt;&lt;/script&gt; </code></pre> <p>My Index.html is as below:-</p> <pre><code> @{ ViewBag.Title = "Receive Error message"; Layout = "~/Views/Shared/_Layout.cshtml"; } &lt;script src="/signalr/hubs" type="text/javascript"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(function () { var myHub = $.connection.messageHub; myHub.pushMessages = function (value) { console.log('Server called addMessage(' + value + ')'); $("#messages").append("&lt;li&gt;" + value + "&lt;/li&gt;"); }; $("#btnMessage").click(function () { myHub.message(); }); $.connection.hub.start().done(function () { alert("Now connected!"); }).fail(function () { alert("Could not Connect!"); }); }); &lt;/script&gt; &lt;h2&gt;Receive Error Messages&lt;/h2&gt; &lt;ul id="messages"&gt;&lt;/ul&gt; &lt;input type="button" id="btnMessage" value="Get Error" /&gt; </code></pre> <p>In Global.asax I have written </p> <pre><code>SignalR_Error_Logging.SignalRHub.MessageHub hub = new SignalRHub.MessageHub(); hub.Message(); </code></pre> <p>In Application_Start();</p> <p>I am not able to display message in my UI(i.e Index.cshtml). </p> <p>Things that i have tried:-</p> <ul> <li>Running the application as IIS.</li> <li><p>Changing the way of creating HubContext.</p> <pre><code> IHubContext _context = GlobalHost.ConnectionManager.GetHubContext&lt;MessageHub&gt;(); context.Clients.notify("Hello world"); </code></pre></li> <li><p><code>if (Clients != null) { Clients.shootErrorMessage(message); this.Clients.shootErrorMessage(message); }</code></p></li> <li><p>Gone thru links of Stackoverflow<a href="https://stackoverflow.com/questions/7634255/calling-signalr-hub-clients-from-elsewhere-in-system">Calling SignalR hub clients from elsewhere in system</a></p></li> </ul> <p>Any advice???</p> <p>When i call my hub method by creating a button in Index.html it works fine.</p> <p>Apologies for not framing my question properly!!</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).
