I m having problem when implementing autocompleteextender in visual studio 2008, where when i enter my any text in my textbox,it will automaticly capture the keywords and suggest words from database..no errors found,but it didnt works when i enter any keyword inside the textbox..
This is my aspx file :
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="AutoComplete.asmx" />
</Services>
</asp:ScriptManager>
<div>
<asp:TextBox runat="server" ID="myTextBox" Width="300" autocomplete="off" />
<ajaxToolkit:AutoCompleteExtender
runat="server"
ID="autoComplete1"
TargetControlID="myTextBox"
ServicePath="AutoComplete.asmx"
ServiceMethod="GetCompletionList"
MinimumPrefixLength="2"
CompletionInterval="1000"
EnableCaching="true"
CompletionSetCount="12" />
</div>
</form>
</body>
</html>
This is my asmx.cs file:
using System;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
/// <summary>
/// Summary description for AutoComplete
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class AutoComplete : System.Web.Services.WebService
{
[WebMethod]
public string[] GetCompletionList(string prefixText)
{
DataSet dtst = new DataSet();
SqlConnection sqlCon = new SqlConnection(ConfigurationManager.AppSettings["%$ ConnectionStrings:C:\PROGRAM FILES\MICROSOFT SQL SERVER\MSSQL.1\MSSQL\DATA\DATABASE1.MDFConnectionString %"]);
string strSql = "SELECT Company_Name FROM Table1 WHERE CompanyName LIKE '" + prefixText + "%' ";
SqlCommand sqlComd = new SqlCommand(strSql, sqlCon);
sqlCon.Open();
SqlDataAdapter sqlAdpt = new SqlDataAdapter();
sqlAdpt.SelectCommand = sqlComd;
sqlAdpt.Fill(dtst);
string[] cntName = new string[dtst.Tables[0].Rows.Count];
int i = 0;
try
{
foreach (DataRow rdr in dtst.Tables[0].Rows)
{
cntName.SetValue(rdr["CompanyName"].ToString(), i);
i++;
}
}
catch { }
finally
{
sqlCon.Close();
}
return cntName;
}
}
Should i modify any code part?
Can i use the autocompleteextender using sqldatasource to call database?
Any ideas will be much appreciated.
