Strictly speaking, not. But why would you want it, just to make you work a nightmare? :-)

You dont have to add the reference like that. Just adding the webmethod and assigning to the autocomplete extender will do.

Hi,

If that web service is along with your project or solution, You don't want add as a web service reference / sevice reference to your project.

Example you can use webservice,

1. using Ajaxtoolkit

VB

<asp:AutoCompleteExtender ID="txtSearchPanel_AutoCompleteExtender" runat="server"
  ServiceMethod="GetCompletionList_Popup" ServicePath="~/AutoComplete.asmx"

2. using javascript

XML

<script language="JavaScript">
init(){
 service.useService("http://localhost/CursoAspNetWebService/Service1.asmx?WSDL",_
                                                                     "Service1");
}
function tst(){
   iCallID = service.Service1.callService("Suma",ip1.value,ip2.value);
}
function onmyresult(){
   service.innerHTML= "Resultado : " + event.result.value;
}
</script>
<body onLoad="init();">
  <button onclick="javascript:tst()" ID="Button1">Call Add Web Method</button>
  <div id="service" style="BEHAVIOR:url(webservice.htc)" onresult="onmyresult();">
  </div>
</body>

It basically depends on web service, if it is a Restful or ajax enabled service then you don't have to add its reference, you can directly call it using HTTP Get/Post protocol. If it is not a restful or ajax enabled web service then you have to call it by adding its service reference.

The following code will show how to call a restful web method.

//Get method

WebRequest req = WebRequest.Create(@"http://localhost:61447/Products.svc/");
 
req.Method = "GET";
 
HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
if (resp.StatusCode == HttpStatusCode.OK)
{
    using (Stream respStream = resp.GetResponseStream())
    {
        StreamReader reader = new StreamReader(respStream, Encoding.UTF8);
        Console.WriteLine(reader.ReadToEnd());
    }
}
else
{
    Console.WriteLine(string.Format("Status Code: {0}, Status Description: {1}", resp.StatusCode, resp.StatusDescription));
}
Console.Read();

Is it necessary to add a web service reference or a simple service reference in a web application to use a web service?
