Why my autocomplete ajax script does not work:
This is my WebService.cs:
using System;
using System.Data;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.ComponentModel;
using System.Data.SqlClient;
using System.Collections.Generic;
using System.Configuration;
using System.Web.Script.Services;
[ScriptService]
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following
line.
public class WebService : System.Web.Services.WebService {
public WebService () {
//Uncomment the following
line if using designed components
//InitializeComponent();
}
[WebMethod]
public string[] GetCountryInfo(string prefixText, int count)
{
string sql = "Select * from questions Where username like @prefixText";
SqlDataAdapter da = new SqlDataAdapter(sql,"estudent_piooConnectionString");
da.SelectCommand.Parameters.Add("@prefixText", SqlDbType.VarChar, 50).Value = prefixText + "%";
DataTable dt = new DataTable();
da.Fill(dt);
string[] items = new string[dt.Rows.Count];
int i = 1;
foreach (DataRow dr in dt.Rows)
{
items.SetValue(dr["username"].ToString(),i);
i++;
}
return items;
}
}
my css:
/*AutoComplete flyout */
.autocomplete_completionListElement
{
margin : 0px!important;
background-color : inherit;
color : windowtext;
border : buttonshadow;
border-width : 1px;
border-style : solid;
cursor : 'default';
overflow : auto;
height : 200px;
text-align : left;
list-style-type : none;padding:0px;
}
/* AutoComplete highlighted item */
.autocomplete_highlightedListItem
{
background-color: #ffff99;
color: black;
padding: 1px;
}
/* AutoComplete item */
.autocomplete_listItem
{
background-color : window;
color : windowtext;
padding : 1px;
}
and textbox:
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" CompletionListCssClass="autocomplete_completionListElement"
CompletionListItemCssClass="autocomplete_listItem" CompletionSetCount="20"
CompletionInterval="1000" DelimiterCharacters=";,:"
CompletionListHighlightedItemCssClass="autocomplete_highlightedList MinimumPrefixLength="1" ServiceMethod="GetCountryInfo" ShowOnlyCurrentWordInCompletionListItem="true" TargetControlID="TextBox2" ServicePath="WebService.asmx" runat="server"></cc1:AutoCompleteExtender>
