I have am trying to implement a simple AutoComplete function yet i am having difficulty. It looks like the AutoComplete control is not even calling the method (webservice). If i load the webservice from the browser, i can see my Method, click on it, enter in the prefix, click on Invoke and it returns a SQL STRING. Below is the string the webservice returns.
<?xml version="1.0" encoding="utf-8"
?>
I'm calling a webservice using jQuery with .ajaxHere are the data parameters for the call:
var parameters = "{'Titre':'" + Titre + "','Description':'" + Description + "','Contact':'" + Contact + "','VilleId':'" + VilleId + "','QuartierId':'" + QuartierId + "','UserId':'" + UserId + "'}";
It works fine. But when parameters Description or Titre contain the ' character , no call!!!
Does anyone have an idea how can i make it work even with apostrophe character in Titre and/or Description?
I have a webservice "DataService.asmx" which I am using for AJAX calls for insert, update, delete and some other tasks.

I am calling a web service via Javascript. I tried it first in a web page that does not have a Masterpage and it worked perfectly. Then I moved everything over to a web page that does use a Masterpage, and I get a "Microsoft JScript runtime error: Object required" on the javascript statement that calls the web service. My javascript statements look like so:

Actually I am trying to learn jQuery Ajax calls to asp.Net webservices.
I have been trying to call the webmethod below:
[code]....
Do I need to serialize my object in some way before setting the 'data' attribute, so that I can call $.ajax() function?
I have a web user control. That I load dynamicaly inside a modalpopup window using dynamic populate extender. User control has a external javascript file linked to it. Problem: I cannot make call to webservice method from this external javascript file. When I make a call -- servicename.methodname() I get servicename not defined error.
View 2 RepliesOn one of my pages I've got a popup window implemented using the ModalPopupExtender. The content html of the popup is retrieved from a webservice dynamically (using DynamicServicePath, DynamicServiceMethod properties of the extender). Everything works fine, however there is a minor problem: web service call takes about 2 seconds and the popup panel is blank during this time, which confuses the users. I would like to display 'Loading...' message in the popup window (or an animated image, does not really matter) during the webservice call. Is there a way to do it?
View 2 Repliesin fact I have 2 webservice calls, one returns 8 results and the other one 4 results. So the same webservice is called twice but with different arguments and on different pages(browsers).What happens? even though I call on one page only one webservice(arguments1), I also get the results from webservicearguments2) which should be only on PAGE2to be more clear: I get both webservice results in both the pages, when I expect one for each page, it's like they share webservice results somehow,
View 3 RepliesPinging back to a webservice in ajax from the client keeps the user's session alive, I don't want this to happen. More extensive summary For a website we're developing, we need the client to ping back (in js) to a webservice (ASMX) on the server (IIS7.5). This happens to let the server know that the user is still on the site, and hasn't browsed away to another site. This is as our customer wants to let users lock records, but if they browse away to other sites, then let other people take over those locked records. Perhaps the distinction between the client being on the site but inactive and on another site seems unimportant, but that's kinda irrelevant, I don't get to write the UI spec, I just have to make it work.
My problem is this, the ping stops the user from being timed out on the server through the standard forms authentication timeout mechanism. Not surprising as there is that 30 second ping in the background keeping the session alive. Even though we want to know if the user is still on the site, we want the normal forms authentication timeout mechanism to be honoured. I thought I might be able to fix this by removing the ASP.NET_SessionId and .ASPXAUTH cookies in the XMLHttpRequest that is the server ping, but I can't figure out how to do this. This is how my web service & method are defined:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService]
public class PingWS : WebService
{
[WebMethod]
public void SessionActive(string sessionID)
{
// does stuff here
}
This is how I'm calling it in js (request is over HTTPS, :
$.ajax({
type: "POST",
url: "PingWS.asmx/SessionActive",
data: 'sessionID=' + aspSessionID + '}',
beforeSend: function (xhr) {
xhr.setRequestHeader('Cookie', '');
xhr.setRequestHeader('Cookie', 'ASP.NET_SessionId=aaa; .ASPXAUTH=bbb;');
},
dataType: "json"
});
I was trying with the setRequestHeader, but that just appends to the header rather than overwrites the header, and IIS is happy to ignore that junk I added. I'm thinking maybe I should be trying to do this at the server end, someone take PingWS.asmx out of the loop so that it doesn't keep the session active, but I'm not sure how to do this. Although the title of the question is focused on clearing the cookie in the header, I'd be super happy if anyone points out that I'm being really stupid and there is actually a much better way of trying to do what I'm doing.
I'm thinking at this stage maybe I need to add something to the webmethod that says how long this particular page has been inactive, and use that knowledge to timeout manually. That actually sounds pretty easy, so I think I'll do that for now. I'm still convinced that there must be an easy way to do what I originally wanted to do though. Update I'm thinking I'm pretty screwed in terms of cookie manipulation here as both the .ASPXAUTH and ASP.NETSessionId cookie are HttpOnly, which means the browser takes them out of your hands, you can't access them via the document.cookies object. So I would say that leaves me with:
Updating my SessionAlive webmethod to track each request so I can tell how long the user has been sitting idle on a page and timeout if needs be Marking the .asmx page somehow on the server end so that it's taken out of the normal authentication/session tracking flow I know how to do 1. so I'll start there but 2. seems much cleaner to me.

I have to call a webservice published in the same website the caller aspx is. When I try to "Add a Web Reference" the editor does not show the webservice methods from the generated namespace. Do I have to use the "Add Web Reference" or is there another way because the webservice is in the same website? Visual Studio 2005, C#

how to call web service with jquery in asp.net with param value
View 7 RepliesI need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:
"data" : "my data"
This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.
string data = "test";
Uri address = new Uri("http://localhost/Service.svc/json");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
string postData = "{"data":"" + data + ""}";
How can I add my json data to my request and then parse the response?
Can I call a webservice from a Controller Action in ASP.Net MVC?
public ActionResult Index()
{
PersonObject person = new Person("Sam");
//Call a webservice which is located in the same app under /Services/General.asmx/WebMethod and pass it person
}
Basically I want to do this from my Action...
$.ajax({
type: "POST",
url: "/Services/General.asmx/WebMethod",
data: JSON.stringify(DTOInternetPricing),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(res) {
},
error: function(res) {

});
I have MVC application (applies to non MVC as well) where a user is posting in data. I need to take this data, send it off to two seperate end points (one using a WebRequest form POST and one using a Web Service), parse the result, and send the result back to the original user.
The issue at hand is that both end points take about 20-30 seconds to respond (response is a string) which means that I should probably execute these two calls asynchronously. At the same time I want to wait to respond to the original user until I get both results back. I am guessing I might have to use some sort of object lock so the response does not get sent back before the two calls are complete?
Based on the responses I decided to go with async controllers since I am already working with a MVC application.
I've enhanced my web service with a new method. If I open a browser and type the url of the service, I get a list of the methods including the new one, so that looks okay.
I have a snippet of code which I paste to a Firebug console to test the method, and I am getting a 500 internal server error. If I use the same snippet of code and modify it to test one of the other methods, that works fine.
What I can look at to figure out what is wrong with this new method? The other weird thing is if I try to run the URL on the server it says The test form is only available for requests from the local machine. But I am on the local machine. So I don't know if something is screwed up there, too, or it's the same cause or what.
I know there's tons of advice on the Internet regarding server 500 errors but this is unique in that my web service is working except for the new procedure.
I think I will write another new procedure that's simple (like Hello World) and see if I can call that. This new method returns a list of objects but so does one of the older methods, so I don't know what would be unusual there
I am trying to use Jquery Validate and making a call to a webservice to validate a field. But when I do this I get the Firebug error :

I've created a small class library to asynchronously call a WebService(Fire and Forget. I don't need the result).In a Windows Form application, the XXXAsync() method works fine. But, in a Web Application, the process is locked until the XXXCompleted event is fire.My problem is: I tried to create a Delegate and use the Begin/EndInvoke to call the XXXAsync() method. It worked fine, but, the w3wp process seems to be consuming a huge amount of memory. I'm calling the EndInvoke method properly. Invoking the GC.Collect did not free any memory
