So for testing purpose I try with small amount of data and it start working. So now I think I should use Like Query in my webservice and only return top 10 data only. So what i need do is that whatever i type in textbox it should go to webservice and webservice with filter the data will send back to us. But how can I achieve this. I am using following codes

ASPX Page Code

2. <script type="text/javascript">
3.         $(document).ready(function() {
4. 
   
5.             //Code to fetch
6.             $.ajax({
7.                 type: "POST",
8.                 url: "../AutoComplete.asmx/GetCompletionActorList",
9.                 dataType: "json",
10.                 data: "{}",
11.                 contentType: "application/json; charset=utf-8",
12.                 success: function(data) {
13.                     $("input#actorList").autocomplete({
14.                         source: eval(data)
15.                     });
16.                 },
17.                 error: function(XMLHttpRequest, textStatus, errorThrown) {
18.                     alert(textStatus);
19.                 }
20.             });
21.         });
22.     </script>

WebService Code

2.  <WebMethod()> _
3.   Public Function GetCompletionActorList() As String
4.     Dim sbActor As New StringBuilder()
5.     Dim actorAPI As New ActorBLL
6.     Dim actor As Q8movies.ActorDetailDataTable = actorAPI.GetActorDetail()
7. 
   
8.     Try
9.       sbActor.Append("[")
10.       For i As Integer = 0 To actor.Rows.Count - 1
11.         sbActor.AppendFormat("'{0}',", actor.Rows(i).Item("ActorName"))
12.       Next
13. 
    
14.       'Removes the extra ":"
15.       sbActor = sbActor.Remove(sbActor.Length - 1, 1)
16.       sbActor.Append("]")
17.     Catch ex As Exception
18.       'Setup a breakpoint here 
19.       'to verify any exceptions raised.
20.       Dim exp As String = ex.ToString()
21.     End Try
22.     Return sbActor.ToString()
23.   End Function
24. 
    

In above webservice code I will add parameter to the function so it will return less records. I also want to work on the CSS of the auto complete so kindly help on this.
