    <p>I have a very simple AJAX example that doesn't work. It is from the Microsoft tutorials on AJAX.</p> <p>When I click on button "Button1" AJAX should execute but the whole page submits.</p> <p>Here is the code:</p> <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="1111.aspx.cs" Inherits="_1111" %&gt; &lt;%@ Register Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Namespace="System.Web.UI" TagPrefix="asp" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;p&gt; DropDownList AutoPostBack SelectedIndexChanged EventArgs Sort ... Since you will be using AJAX to process your SelectedIndexChanged event, set the AutoPostBack property of the DropDownList to false. ...&lt;/p&gt; &lt;div&gt; &lt;asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"&gt; &lt;/asp:ScriptManager&gt; &lt;asp:Label ID="label2" runat="server"&gt;&lt;/asp:Label&gt;&lt;br /&gt; &lt;asp:Label ID="label3" runat="server"&gt;&lt;/asp:Label&gt;&lt;br /&gt; &lt;center&gt; &lt;asp:UpdatePanel ID="UpdatePanel1" runat="server"&gt; &lt;ContentTemplate&gt; &lt;asp:Label ID="label1" runat="server"&gt;&lt;/asp:Label&gt; &lt;asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button 1" /&gt; &lt;/ContentTemplate&gt; &lt;Triggers&gt; &lt;asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" /&gt; &lt;/Triggers&gt; &lt;/asp:UpdatePanel&gt; &lt;/center&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Code-behind: </p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _1111 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { label1.Text = System.DateTime.Now.ToString(); label2.Text = System.DateTime.Now.ToString(); label3.Text = System.DateTime.Now.ToString(); } protected void Button1_Click(object sender, EventArgs e) { label1.Text = System.DateTime.Now.ToString(); } } </code></pre>

    1. CONot wanting to be a nitpicky language nazi type, but your title is very wrong. Asp.Net AJAX very much works, as millions of developers make use of it daily. More specifically your install of ASP.net AJAX doesn't work, but even that may be false, as it could be a misconfigured server, a coding error, a browser with scripting disabled, or any other number of things that cause the problem. A *much* better title would have been, "ASP.NET AJAX code is still causing full postback" for example.

    3. COjusted pasted your code into an asp.net ajax project in VS2008 and it does callbacks not postbacks, i.e., works as expected

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
