Hi,

I am currently working on ajax auto complete extender. I want to show list of places using WCF. I have two separate project, one for website and other for WCF and I am using fiddler to trace the request and response.

The project is error free. But when i type something inside the text box, the auto complete list is not displayed. But i can see the response inside fiddler. I am trying to access the WCF service through the ServicePath and Service method property of autocompleteextender as shown below:

ASP.NET

<ajaxControl:AutoCompleteExtender  runat="server" ID="txtAutoCompExtAjax" TargetControlID="txtAutoCompExt" 
            ServicePath="http://localhost:2027/HotelService.svc" ServiceMethod="GetLocation" UseContextKey="true"
                MinimumPrefixLength="1" CompletionInterval="0" CompletionSetCount="20" EnableCaching="true" ContextKey="" >
            </ajaxControl:AutoCompleteExtender>

Below is my WCF config file:

HTML

<system.serviceModel>
    <services>
      <service name="HotelService.HotelService" behaviorConfiguration="HotelBehavior">
        <endpoint address="" binding="webHttpBinding" contract="HotelService.IHotelService" behaviorConfiguration="ServiceAspNetAjaxBehavior">
         </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="HotelBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="ServiceAspNetAjaxBehavior">
          <enableWebScript />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"  aspNetCompatibilityEnabled="true"/>
  </system.serviceModel>

I tried to google a lot. Please help.

Just go through the article - Implement ASP.Net AJAX AutoCompleteExtender using WCF Web Service[^].

Just go carefully, see all the configurations are correct in your code or not. Also download the project and try at your end.

I guess you are missing something.

Yes i have gone through this. But if you see carefully inside autocompleteextender control, the service path is the file name and here i am trying to give the link where my WCF is hosted.

Do you see any Error inside FireBug console?

linto_11 31-Dec-13 0:30am

no error in fire bug...in fact while using fiddler i can see the JSON with the value, but it is not getting displayed.

thanks for your answer, but i have gone through the link that you have given on WCF. But if you closely examine the 'ServicePath' attribute inside 'autocompleextender' holds the path of the file and if you can see the attribute that i have give is a 'link'. I think some problem with that...
