AJAX :: Extra Request To A Default Page On A Callback?
Sep 25, 2010
I have a following issue (it's only happening in Internet Explorer).
I add callback to a page in the old-fashioned way -> Page.ClientScript.RegisterClientScriptBlock(...)
The scenario is: 1) The default page is being loaded. On Page_OnLoad it assigns a NULL to some session key. Let's call it Control -> Session["Control"] = null;
2) User presses a button and gets redirected to a next page (let's call it NextPage.aspx) using javascript event -> window.location.assign(....) (also tried .href = ... - no help)
3) The NextPage.aspx assigns some value to Session["Control"] on Page_OnLoad
5) User clicks a button on the NextPage.aspx and a callback request is being sent to a server....
TA DA!!! The interesting part:
6) Along with the request to the NextPage.aspx another request is being sent to the default page.
7) The only response is being recieved by a client is a response from the NextPage.aspx BUT since the code on the default page is being executed it puts null to the Session["Control"] which screws all my following scenario. the default page doesn't recognize the request as a callback? so if(IsCallback) {} doesn't help....
I believe it's not a code issue since as I wrote above it works in development environment,but I have no clue what can 'cause it to fail in production and only in IE...
At least what to start to look at... and I have Helicon's ISAPI Rewrite installed on the production server. It doesn't seem to be the cause but who knows....
Correction
if I do not assign window.location and just add a link to the NextPage.aspx and click it manualy after callback ended it still sends extra request to the default page. if I click the link before I initialize callback it works fine without extra request.

I have a simple script making a request to the server:
var DTO = { 'path': path };
var url = 'default.aspx/Get';
var test;
$('#getInstance').click(function () {
$.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(DTO),
contentType: 'application/json; charset=utf-8',
success: function (msg) {
test = msg;
},
error: function (jqXHR, textStatus, errorThrown) {
alert(textStatus);
alert(errorThrown);
}
});
});
This works fine as in it connects to the server and gets the data back, with one simple problem. It is treating this request as a cross domain request, therefore using jsonp. The server code is here:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static MyObject Get(string path)
{
MyObject foo = new MyObject();
return foo;
}
Normally this would not be a problem, except that I am accessing a WebMethod, and it doesnt have the capability to return a jsonp response (meaning it has no way to attach the callback function to the response. Now, if this was a manual response, I could hack it up and attach the parameter, but I am taking advantage of the built-in serialization, so no way to mess around with the response. [URL]
Let me just stress the fact that this code works. The only problem is jQuery treating this request as cross domain. But Why? UPDATE: Well, after many more hours and more testing I have narrowed this issue down to it being a bug in jquery 1.5.1. I did some testing with older versions (all 1.4 versions) and I had no problem, the request was made using JSON, and the response was received successfully. What could be the change they made that would consider this request a CORS?

Ive set up a basic client side callback to a WCF service. see sample code below.
when viewing using an http filter attached to the explorer you can see that:
1. service1.svc/js is working fine and return proper java script to the browser
2. serrvice1.svc works and returns a proper json data.
3. call is fine and using alert instead of updating the div info i get the data.
but then after OK on the alert the page is then reloaded from scratch.

I have a small part of my page existing on the master page. this small portion is embeded within an update panel that I postback using asynchronus postback. The problem is that; my default.aspx page which uses the master page gets affected (i.e I lost the text in the textboxes) on the asynchronus postback although the update panel doesn't include these textboxes. Is there a solution to ensure that postback only affects this part of the page?

I'm using the MVC2 framework and one of my views has a bit of conditional logic that gets the Page.User.Identity object and does a comparison with other values to determine what to display.That all works fine on the initial page load, but when I make an AJAX call to get partial page updates (I'm doing this all manually with YUI3, not the .NET AJAX stuff) the Page.User object is always null.

When user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have an AJAX controller action which returns JSON. The returned JSON is handled via jQuery and contains a message displayed in an update div. The JSON also contains a flag which indicates a change in state. If this is true the entire page needs to be reloaded from a different url. This is currently performed in the jQuery using window.location.replace(url). In the situation where a full page refresh occurs, I still want to display the message from the JSON in the update div, but after the page has fully reloaded.
How can I ensure the div is updated with the message after the window.location.replace call and the page has been completely reloaded? (I realise AJAX is not intended for full page refreshes but I can't think of a simple way of avoiding it in this scenario. Normal behaviour here is updating the div with a status message.)

I'm developing a pretty standard MVC application.. I've set the routing up as follows:

Everything works perfectly in all browsers - apart from IE. If I am on, say, Stock/Index/, it will fire the Stock/Index/ GET request, then fire the Stock/NewLines/ request afterwards..Obviously this isn't desired behaivour - as I understand it, the default route value is for when the router can't find the requested controller/action/route, and so sends the request there..Can't seem to find any info on the web about this,

I use ASP.NET Ajax in my web site and I am monitoring the HTTP requests per each page. I am surprised by the excessive call of ScriptResource.axd with different query string variables. I am pasting a sample of HTTP trace below. The call for ScriptResource.axd take lots time percentage out of total response time. Is this by design or there is something wrong with my AJAX configuration in web.config?

Actually it is degrading the performance of the application. And the user experience becoming very poor in case of lower bandwidth.

Whenever a postback would occur (AJAX'ed by an UpdatePanel) I want to do a callback beforehand and only after the callback has completed (either successfully or not) should the postback occur. How can I do this?
Elaborate explanation: We use ASP.NET AJAX (UpdatePanel 'n stuff) together with DevExpress controls. Among those controls is the ubiquitous GridView. As is typical with ASP.NET gridviews, you can edit rows one-by-one, and to save your changes you have to hit the "update" button at the end of the row. However if you make some changes to the row, then forget to press the "update" button, and hit something else in the page (say the big red SAVE button that causes a postback and saves the whole form to the DB), your changes will be lost. The row will still be in edit mode, but it will have reset to the data it had initially when you started the edit.
Our clients are not happy with this and want the row to be saved automatically if the user forgets to do so himself. Luckily the DevExpress gridview is smart enough to have an "Update()" method which I can call from JavaScript. Unluckily that causes a callback and returns immediately. If I allow the postback to continue as normally, the callback will get aborted. Well, technically it's a race condition I guess, but so far it seems that the postback wins. There are events to which I could attach for success/failure of the callback, but I don't know how to "resume" the postback that started it all. We could turn off callbacks for all the grids, but that would be a performance disaster.

I have an asp.net page. I'm using a jquery library to open a modal window on link click. Within this modal window I'm loading another page. After i make update within this modal window I need to send a callback to "Parent" page. if I call function from this window I'm getting the error it couldn't find function. Window.opener.functionname also not working.
here is an example of my code
$(function () {
$('#ControlId').click(function (e) {
e.preventDefault();
$.ModalWindow({
bgColor: '#3333cc',
url: 'default.aspx'
});
return false;
});
return false;
});
});
Is there any way how to send a callback?

In asp.net is it a requirement to rebuild the whole page during every callback? For example my web page is split into three distinct areas and I have an update panel for each area. Lets say I want to update the third area, do I have to bother with any processing of the other two areas?
For example lets say there is a grid view in area two. The update panel in area three callbacks to update its content. Do I have to rebind the grid in area two?

I have a previously working ASPX website which also supports AJAX. However, we just upgraded our SQL Server from 2008 Evaluation to 2008 R2 version 10.50.16 and now this website is no longer working. I believe the problem is that now we need to again restore original SQL accounts and settings prior to this upgrade. This website also uses AJAX. Which accounts need to be created to fix this problem? When I navigate to this URL, I get the message below:
The address is not valid.

I have a updatepanel which contains of a few dynamically created ImageButtons (the ImageButtons are placed in a panel inside the updatepanel) Since the imagebuttons are children of the updatepanel they automatically triggers a callback to server, fine. But I want the user to be able to cancel the callback after clicking on the imgbutton, preferably through a javascript window.confirm.
I have managed to make it work with a jquery function returning false (i dont know why it works, dont really understand asp.net ajax functionality) but it only works until a callback is done, then I guess I have to rebind the jquery to the controls in the updatepanel or?this turned out to be a jquery question. How do I rebind the recently loaded controls in my updatepanel to my jqyery function? the controls all have the same class and I use that to trigger the jquery function.
aspx file
..
..
$('.myImgButtons').click(function(){
if(window.confirm('Cancel callback?') )
return false;
});
..
..
<asp:UpdatePanel ..... >
<ContentTemplate>
<asp:panel id="myPanel" ........ ></asp:Panel>
</ContentTemplate>
<Triggers>
..whatever..
</Triggers>
</asp:UpdatePanel>
aspx.cs file
..

ImageButton dyn_ImgButton = new ImageButton();
dyn_ImgButton.Attributes.Add("class", "myImgButtons");
add dyn_ImgButton to myPanel

I'm using ajax to call a webmethod from javascript. The call is successfully made to the webmethod but I'm not able to access the parameters I passed to the webmethod inside of the "OnSucceeded" callback method. I need access to those params because I need to perform more tasks on the client side when the webmethod returns. I'm assuming that the params are returned inside "usercontext", but the value of that param is "null" How can I have access to those params?
Here my sample code:
function OnSucceeded(result, usercontext , methodName)
{
alert( result + ' The value of usercontext is: ' + usercontext);
}
function OnFailed(error, userContext, methodName)
{
alert('Attempt to delete semantic attribute from page failed!');
}
function deleteSemanticAttribute()
{
var username = 'xxxxxx';
var password = 'yyyyyy'
PageMethods.GetMyData(username, password, OnSucceeded,OnFailed);
}
[WebMethod]
public static string GetMyData(string username, string password)
{
return "This is my test application!";
}

I have Russian blog built with BlogEngine.NET 1.5.
I use Russian words in links encoded with URLEncode, so links are human-readable in most browsers - FF, Chrome, Opera (except for IE, but this is not the real problem with this browser). This idea is not mine, I borrowed it from Wikipedia - it uses encoded URLs on localized sites.
The real problem is that when I am trying to add comment in IE8 it fails (and only on production machine, development environment works fine).
Using Fiddler I found out that IE tries to send AJAX callback using WebForm_DoCallback to wrong address - it seems that it decodes URL, gets wrong characters and asks page with that wrong address from server and (of course) receives 404.
Here is how incorrect request from IE looks in Fiddler:
POST /ru/post/�������������-�����.aspx HTTP/1.1
Here is how FF makes same request and gets correct response:
POST /ru/post/%D0%92%D1%81%D1%82%D1%83%D0%BF%D0%B8%D1%82%D0%B5%D0%BB%D1%8C%D0%BD%D0%BE%D0%B5-%D1%81%D0%BB%D0%BE%D0%B2%D0%BE.aspx HTTP/1.1
I upgraded solution from default ASP.NET 2.0 for BE to ASP.NET 3.5 but this changed nothing. I made some minor changes in BE to allow properly encoded UTF links - by default it wipes out percent symbol from links.
what wrong is with IE behavior here and how to fix it? Why development environment under ASP.NET Development works different from production machine under IIS6? Why IE does not decode link in address bar (like other browsers) but does it when making request?
