There is no sample coding for ASP.NET AJAX based autocomplete textbox using VB.NET. I tried a lot in order to identify the following working code. Hope this will be very much useful to all. All the best.
Declarations:
Here is the Code to be written in Web Service file. ' Note, by default while we create the webservice, ' it does not add the script serivce line. ' We need to add it manually. ' Without this line the code will not work. ' <System.Web.Script.Services.ScriptService()> Imports System.Web Imports System.Web.Services Imports System.Web.Services.Protocols <WebService(Namespace:="http://tempuri.org/")> _ <WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _ <System.Web.Script.Services.ScriptService()> _ Public Class AutoComplete Inherits System.Web.Services.WebService Private Shared autoCompleteWordList As String() <WebMethod()> _ Public Function GetWordList(ByVal prefixText As String, ByVal count As Int16) As String() Dim S(count - 1) As String Dim I As Integer For I = 0 To count - 1 S(I) = prefixText & " " & Environment.TickCount Next Return S End Function End Class
Code:
' This code is to be placed in the aspx. <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <br /> <div> <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="GetWordList" ServicePath="AutoComplete.asmx" TargetControlID="TextBox1"> </cc1:AutoCompleteExtender> <asp:Panel ID="Panel1" runat="server" Height="160px" Width="464px"> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><asp:TextBox ID="TextBox1" runat="server" Width="352px" > </asp:TextBox><asp:Button ID="Button1" runat="server" Text="Button" /></asp:Panel> </div> </form>
