AJAX :: Calling A Web Service From Extender
Apr 8, 2010
VS2008
Using C#
AJAX Toolkit 20229.20185
I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.
Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error
Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]

I have one asp.net application, in which i am using "Calling WCF Service Operations in AJAX" method. I finished my work without the service hosting in IIS. I got the correct solution. But now, i have another requirement in which i am using the WCF service which is hosted on local host iis. But in clicking the button i got one javascript error like object expected. I don't know why this happened?
My code is shown below.

I am trying to call an asmx service using the jQuery ajax call-
[Code]....
I have double checked the url of the service and spelling/case of the name of the method as well as the parameters in the dataStr.
I still get the error-<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.
in the responseText of XMLHttpRequest, above.

I am new to Silverlight. In Silverlight, we can get data from server using ASP.Net (using WebClient and HTTPWebRequest classes in Silverlight) and using WCF Service.
Assuming that I do not need the cross domain capability, what is a good option in terms of Security and ease of development?

I am in the process of implementing jQuery calling WCF service which is hosted in the same domain. My application uses Win Auth that works fine with ASP.NET app. I would like to know from the team if the user calls the WCF service from the ASP.NET what is the security context in which the service runs? Or it uses the web.config security which is specified? Are there any links related to this where i can get some information.
ASP.NET 4.0, jQuery and WCF 4.0 in same web application

I am developing application for PDA. The Sql Server compact edition is installed on PDA. The data is stored on PDA's DB as well as the Server Database through wifi.
If the server is available,the data will be stored through web service, If not available ,the data should be inserted when the server is connected to the data.
which is better to transfer data whether the web service or windows service?
If web service means, how could i transfer the data to server database?

I have almost the same problem as you have described in [URL] service. I have a asp.net webservice that calls a WCF service. On my development machine this is working fine. But if i deploy my ASP.net Webservice it is not working. Both the ASP Webservice en WCF service needs my cridentials. How did you solved your problem. In the logging of the WCF service I see that my credentials is not passing to WCF.

I have a simple ASP .NET web service running and I want call it from a php client. I m using nusoap soap client.
The following is the client side php code:
<?php
require_once('lib/nusoap.php');
$wsdl="http://localhost:64226/Service1.asmx?wsdl";
$client=new soapclient($wsdl, 'wsdl');
$param=array('number1'=>'2', 'number2'=>'3');
echo $client->call('add',$param);
?>
The web methods I have created in web service are as follows:
namespace WebService3
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{.........
However when I run the above php code it does not return the added value of the passed parameters. Instead it previews the word 'Arrays' I m not experienced in php programming. Am I doing something wrong the above codes?
