I have register.aspx at root level folder and updateprofile.aspx in folder /secure/user/ .
pagemethods are working good at root level folder aspx pages only.
pagemethod calling webmethod in updateprofile.aspx is not working. Getting "undefined" exception.
Why is this so?
I have a page method which take in a complex parameter how can i call this page method using jquery.
This is my page method
[Code]....
and these are my types

I have a long running process that i kick off with a pagemethod that normally takes about an hour to complete, when it is finished it returns the result of the method.I then poll with another pagemethod to update the status of the first process.the process is taking 4.5 hours this week which is acceptable and understandable, but the feedback sometimes gives up after a couple of hours and sometimes the main method never returns any feedback to the client.
Regardless of the lack of status updates and final feedback the server still completes the long task.As far as i'm aware we have made no changes to any timeout values.is there a timeout setting that we are hitting that is above 1 hour for ajax methods?
I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data
{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}
The Response Header states the content type as
"Content-Type application/json; charset=utf-8"
However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?
I have a PageMethod that works perfectly well when it either (a) running in the VS dev server, or (b) deployed but marked with UseHttpGet=false.
What doesn't work, and is driving me mad, is having UseHttpGet=true and then deploying it to a test server (Vista & IIS7). It fails to call through the proxy with error code 404 coming back. But it works find if I set UseHttpGet=false.
I have gone through all of the basic stuff I can think to check, and as noted it works perfectly well on the dev box. So there must be something particular about full-blown IIS7 and its config that I am missing..
anything to check in the IIS manager that would cause this to fail? I've tried with forms authentication enabled and disabled, as a few posts mentioned issues with that.
I have a page that requires user login via Forms Authentication. Is it possible to use Page Methods in this page? My current attempt is resulting in the following error:Message: Sys.Net.WebServiceFailedException: The server method 'GetPlanContent' failed with the following error: System.InvalidOperationException-- Authentication failed.
View 2 RepliesI put my ScriptManger on the top level Masterpage with EnablePageMethods set to "true".2. I put a AutoCompleteExtender (AjaxToolkit) on a second level Masterpage which derives from the top level MasterPage. The AutoCompleteExtender is used for search with a TextBox. The PageMethod is defined in the Code Behind of this second level Masterpage.3. I have several Contentpages that derive from the second level Masterpage.Problem: The AutoCompleteExtender does not work and that's probably because the PageMethod is defined in the second level MasterPage in the CodeBehind and not in the Contentpage. Ok, so I'm pretty sure what causes the error,- I do not want to use a WebService, because I don't want the search to become public. And as far as I know you can't define a WebService that is only visible to the Website itself - it's always public.- It would be stupid to put the search on every Contentpage just for the PageMethods sake.

View 1 RepliesI have written an application that relies upon PageMethods. It was working fine in .NET 3.5 where I would rely upon exceptions to signify something failing during the call. I would then alert the user to what ever it was that happened. All was working great. I transitioned to .NET 4.0 as I am intrigued by the Parallel Computing improvements. Now any exception that I throw in the PageMethod in the code behind is met with an Unhandled Exception. Nothing has changed other than the target framework.
View 5 RepliesWe have used the ajax toolkit auto complete extender in an intranet app which uses Windows authentication. The auto complete uses a static page method in the page code behind to get the results. Even though the page containing the auto complete is authenticated by the server and the asp.net session id set in the cookie, the initial requests from the auto complete result in 401.1 and after few attempts result in a 200. This irritates the users of the app. Also later on there are 401.1 happening intermittently among the various 200 there by affecting the responses.
I have verified these responses by using Microsoft Network Monitor,Fiddler and Firebug. Also these entries are present in IIS logs. I tried to implement the same with a script service but that too gives same issues. Our site has lots of ajax features and controls and everything is working fine, only this issue is there.

I have a long running PageMethod defined in the cs that is being called from javascript and after 4 minutes I am getting the below error and 504 status code for my aspx page and onFail callback is raised.

need to send a byte array from javascript into a c# page method. The int and string variables work fine, but when I step through the c# code, the "object" which was the byte array is null, even though I checked to see if it had a value in JS.
var byteArrayObj = GetBinaryDataFromFile(filePath);
var tranAttachmentName = filePath.replace(/^.*\/, '');
PageMethods.AddFileToTran(tranId, tranAttachmentName, byteArrayObj, RefreshPage, onTimeout, onError);

Is it mandatory to pass the Success and Failure method names as parameters while calling server side methods using PageMethods in client script.

I have implemented AJAX for calling server side function using client side function call i.e Calling server side function using javascript tag by using PageMethod in javascript.
I have few question regarding the same implementation.

This FunctionName will be the name of server side function that a developer want to call.
I am using PageMethods to send a few parameters to a webmethod in my codebehind. The method runs a stored procedure and uses the results to build a string that I am returning from the method.
Everything works fine until I try to include too many records in my results..
Once the results I am trying to return hit about 70K, the pagemethod times out even though it is taking about 1 second to process the results.
Is there a buffer limit or limit on the size or results returned from a pagemethod and if so, where can this be set or changed?
Is there a setting in the web.config somewhere to handle pagemethod buffer size?
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.

I need to set a couple of Session vars by calling a PageMethod using jQuery.
The client side js looks like this:
function setSession(Amount, Item_nr) {
//alert(Amount + " " + Item_nr);
var args = {
amount: Amount, item_nr: Item_nr
}
//alert(JSON.stringify(passingArguments));
$.ajax({
type: "POST",
url: "buycredit.aspx/SetSession",
data: JSON.stringify(args),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () {
alert('Success.');
},
error: function () {
alert("Fail");
}
});
}
and the server side like this:
[System.Web.Services.WebMethod(EnableSession = true)]
public static void SetSession(int amount, int item_nr)
{
HttpContext.Current.Session["amount"] = amount;
HttpContext.Current.Session["item_nr"] = item_nr;
}
only, it seems that the Session vars are not set. When I try to Response.Write out the Session vars, I get nothing. I get no errors, and I can alert out the values passed from the onclick event, to the js function, so they are there.

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]

{%>
<%: Html.ValidationSummary(true)%>
