    <p>I have a problem when handling the ReceiveCompleted event of a MessageQueue in ASP.NET. It catches it successfully, but every changes applied to the Controls of the page have no effect.</p> <p>This is what I've got:</p> <h1>.ASPX</h1> <pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False"&gt; &lt;ContentTemplate&gt; &lt;asp:Label ID="Label1" runat="server" Text="Label"&gt;&lt;/asp:Label&gt; &lt;br /&gt; &lt;asp:Label ID="Label2" runat="server" Text="Label"&gt;&lt;/asp:Label&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; &lt;asp:Timer ID="Timer1" runat="server" Interval="3000" ontick="Timer1_Tick"&gt; &lt;/asp:Timer&gt; </code></pre> <h1>.CS</h1> <pre><code>private static System.Messaging.MessageQueue queue; private static String messageContent; protected override void OnInit(EventArgs e) { base.OnInit(e); queue = new MessageQueue(@".\Private$\MyQueue"); queue.ReceiveCompleted += new ReceiveCompletedEventHandler(mq_ReceiveCompleted); queue.BeginReceive(); } protected void mq_ReceiveCompleted(object sender, System.Messaging.ReceiveCompletedEventArgs e) { System.Messaging.Message message = queue.EndReceive(e.AsyncResult); message.Formatter = new System.Messaging.XmlMessageFormatter(new string[] { "System.String,mscorlib" }); Label1.Text = message.Body.ToString(); //Has no effect. The value updates without problem, but doesn't persist after finishing this method. And the Page doesn't refresh with this new value. Label2.Text = DateTime.Now.ToString(); //Has no effect too. Timer1.Interval = 99999; //And this one the same, no effect. messageContent = message.Body.ToString(); //.. But the value stored in this variable does persist queue.BeginReceive(); } </code></pre> <p>I don't why it fails updating those vars. It may be any nonesense, but I'm new to ASP.NET, so any clue will be welcome.</p> <p>Thanks in advance!</p> <p>Pablo</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).
