But the autocomplete feature does not work.</p> <p>The code for the handler is given below:</p> <pre><code> &lt;%@ WebHandler Language="C#" Class="Handler" %&gt; using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data.SqlClient; using System.Text; public class Handler : IHttpHandler { public void ProcessRequest(HttpContext context) { string prefixText = context.Request.QueryString["q"]; string constr = "Data Source=USER\\SQLEXPRESS;Initial Catalog=my_db;Integrated Security=True;"; using (SqlConnection conn = new SqlConnection(constr)) { // conn.ConnectionString = ConfigurationManager // .ConnectionStrings["constr"].ConnectionString; using (SqlCommand cmd = new SqlCommand(constr,conn)) { cmd.CommandText = "select [name] from names where " + "[name] like @SearchText + '%'"; cmd.Parameters.Add("@SearchText", SqlDbType.VarChar, 50).Value = prefixText + "%"; cmd.Connection = conn; StringBuilder sb = new StringBuilder(); conn.Open(); using (SqlDataReader sdr = cmd.ExecuteReader()) { while (sdr.Read()) { sb.Append(sdr["name"]) .Append(Environment.NewLine); } } conn.Close(); context.Response.Write(sb.ToString()); } } } public bool IsReusable { get { return false; } } } </code></pre> <p>the code for the scripting is given below:</p> <pre><code> &lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" %&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;script src="scripts/jquery-1.7.2.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="scripts/jquery-1.7.2.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="scripts/jquery.ui.autocomplete.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="scripts/jquery.ui.core.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="scripts/jquery.ui.position.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="scripts/jquery.ui.widget.js" type="text/javascript"&gt;&lt;/script&gt; &lt;link href="scripts/demos.css" rel="stylesheet" type="text/css" /&gt;" &lt;script type="text/javascript"&gt; $(document).ready(function () { $("#&lt;%= txtsearch.ClientID %&gt;").autocomplete({ minLength: 1, delay: 0, "~/Handler.ashx"}); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; &lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt; &lt;/asp:ScriptManager&gt; &lt;asp:TextBox ID="txtsearch" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Can someone tell me where i am comitting the mistake.</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.

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).
