"Sys" Is Undefined Javascript Error When Run Page By Navigating To URL On Server

Mar 15, 2011

using 2005 I am getting a funny javascript error but not when in debug mode, in debug mode when I'm running the application all is well but when I run the page by navigating to the URL on the server I am getting the javascript error:


'Sys' is undefined

Sys.WebForms.PageRequestManager._initialize('ctl00$middleContent$scrptMan', document.getElementById('aspnetForm'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);

scrptMan is the name of the scriptManager on the page that I declare on the contentPage. Very strange this is only happening when I access this site outside of the Dev environment. Has anyone seen this before?

VS 2010 - Prompt User Before Navigating Away From A Page And Perhaps Stay On Page

May 15, 2012

I need to check information the user has entered on a page against what I have in my database to see if he is entering duplicate data. It is up to him if he wants to proceed or not. I just need to alert him.

The problem is I don't own the button that he clicks so I can't hook up a javascript confirm to the button click. I am running within vendor code. I have an "override PageLoad()" procedure where I can test what page they're currently on. If they are on page "EditForm.aspx" and would normally navigate to "UserFinish.aspx" without any custom code of mine "interfering", I want to test what they've entered on EditForm.aspx and present them with a popup if they've entered duplicate info, and if they click OK button then proceed to UserFinish but if they click Cancel then stay on EditForm.

Page Causes Validation Errors When Navigating To Another Page - Tab?

Mar 31, 2011

I have a couple of pages with standard validation controls such as RequiredFieldValidator etc inside my RadAjaxPanel.As soon as I navigate to another tab in my RadTabStrip the page seems to force validation errors and pretty much "locks" the page even though non of the fields was selected to enter data.Only once all the required fields was entered the page seems to release the "lock" and only then am I able to navigate to another tab / page without even submitting the page.

what might be causing the "lock" and forced validation errors on the page?

C# - Javascript Function To Set Cookie Value?

Nov 8, 2010

I am new to programming and trying to write a javascript function to set a cookie value when a popup button is clicked.

In home.aspx

<input id="btnCanOK2" type="button" value="Close" class="popupButton" runat="server" onclick="return btnClose_Click" />

for this button, i have written a javascript function:

function btnClose_Click()
document.cookie = 'cookieName=closed; value=dontshowagain';

In merchant.login page

In the code behind of the other page, it has to check if the value of the cookie is set to "dontshowagain". If it is set to the value, the function should not show the popup again. My task is not to show the popup in different pages. If it is closed once, it has to stop showing again until the browser is closed.

if (Request.Cookies["closed"] == null)
else if(Request.Cookies["closed"].Tostring() == "dontshowagain")

Where am i doing wrong?? Now Cookie value is always null :(

Read Flash Cookie From Javascript

Oct 27, 2010

We have a flash video that was created for our project, we dont the source so we have to work around the compiled flash file. We are going to host the video on our domain and the video creates a sol cookie (flash cookie) file to store how far the user has proceeded though the video. So my plan is to access this cookie to see how far the user has progressed and then fire an event when they have finished the movie.

I have been googling for some help but haven't found to much. I have found out that its possible to do in javascript and I have found some .net sol file viewers but haven't seen any examples I can get my mind around. I have watched the traffic that gets created with fiddler and every time the next button is clicked a new request is fired with the swt file that is being accessed. I would also be happy with tracking every time one of these swt files has been accessed as well.

Javascript - JQuery Tabs - Using The Cookie Option Breaks GUI

Feb 16, 2011

I've got a tabbed GUI on a webpage using:

JQuery 1.4.2
JQuery-UI 1.8.9 (full download)

The IDs for the 'pane' divs are GUIDs of domain objects in a database. Everything works as it should. But when I include the cookie option in the function call on

$(document).ready(function () {
//$("#tabs").tabs(); //Without tabs works fine
$("#tabs").tabs({ //This call with cookie option breaks everything.
cookie: {
expires: 1

By 'breaks' I mean - the contents of my final tab (which includes a 'submit' button) ends up being displayed at the bottom of every tabbed page although the tab itself looks fine. None of the tabs open the corresponding pane when clicked, but I can see the correct tab id in the address bar on the browser when I click a tab. I've compared the source of both pages (with and without the cookie option) and they are identical apart from the call to the JQuery tab function. But the Javascript console reports an error: cannot call method 'apply' of undefined

Is there something else I need to do to get this to work? The documentation suggests not. I've inluded the cookies plugin as suggested by Nalum, but this hasn't solved the problem. Drilling into jquery-ui-1.8.9.custom.min.js gets me the offending bit of code:

return d.cookie.apply(null,[b].concat(d.makeArray(arguments ...

This code seems to be expecting [b] to be something like ui-tabs-1 which is the way in which the tabs are IDed if you add tabs via the tabs.add(...) function. And of course I don't add my tabs this way - all my tabs have GUID IDs which are related to elements which come from a DB and are output by a Repeater control.
Some HTML below for reference:

<div id="tabs">
<a href='#TabDiv471de30d-aaec-4485-8a50-1b2fdbc58053'>
Tab A
<a href='#TabDiv951e2fee-9272-4a8c-becb-3f3a07770347'>
Tab B
<div id='TabDiv471de30d-aaec-4485-8a50-1b2fdbc58053'>
This is Pane A
<div id='TabDiv951e2fee-9272-4a8c-becb-3f3a07770347'>
This is Pane B

State Management :: Remove Item (Cookie) From Basket (Cookie Collection)?

I am busy building a shopping cart with cookies. I have datalist which I populate from the cookies with a delete button next to each cookie


Now the problem is that when I hit the delete / remove button to expire the cookie, what happens when repopulating the datalist is that it shows the original cookie with all it's values as well as a new entry where all the values are blank.

State Management :: Updating Cookie / Change The Value In A Cookie?

May 10, 2010

I want to change the value in a cookie:
HttpCookie hc = new HttpCookie("HiddenColumns");
hc.Value = customView.HiddenFields;
hc.Expires = DateTime.Now.AddDays(365);

Or this way:

Response.Cookies["HiddenColumns"].Value = customView.HiddenFields;;
Response.Cookies["HiddenColumns"].Expires = DateTime.Now.AddDays(365);

But when I retrieve the cookie value, it is still old, unless I do postback. I don't want to use Redirect.

WCF / ASMX :: Cookie Refuses To Get Set When Asking For A Cookie From Webservice

Jun 8, 2010

I'm trying to use a webservice that first expects the clients to login, to retrieve a cookie to re-use.
This is done through a login(string user, string pass) method on the webservice.

Doing this through a browser works fine, we get a cookie, and we can see the cookie via Fiddler or whatvever proxysniff thingy.

Time to do the same in ASP.Net, so we use the WSDL and generate a nice proxy class, and it works fine to call the login() method, but Never Ever does a cookie get set !

I already used the "cookiejar" technique - which means i create an instance of a CookieContainer and assign it to the proxyclass like this;

var cookies = new CookieContainer(3);

How To Find The Cookie In IEs Cookie-store

Jun 14, 2010

I am a bit baffled here; using IE7, ASP.NET 2.0 and Cassini (the VS built-in web server; although the same thing seems to be true for "real" applications deployed in IIS) I am looking for the session-id-cookie. My test page shows a session id (by printing out Session.SessionId) and Response.Cookies.Keys contains ASP.NET_SessionId. So far so good.

But I cannot find the cookie in IEs cookie-store! Nor does "remove all cookies" reset the session (as it does in FF)... So where - I am tempted to write that four letter word - does IE store that bloody cookie? Or am I missing something? By the way there is no hidden field with a session id either, as far as I can see. If I check in FF there is a cookie called ASP.NET_SessionId as I would expect. And as mentioned above deleting that cookie does start a new session; as I would expect.

Cookie Isn't Updated Until Page Refresh - How To Avoid That

Feb 16, 2011

I have some pages that read and write cookie values. During the life cycle of a page it may update the cookie value and then need to read it again further in the code. What I've found is that it's not getting the latest value of the cookie until a page refresh. Is there a way around this? Here's the code I'm using to set and get the values.

public static string GetValue(SessionKey sessionKey)
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
return string.Empty;
return cookie[sessionKey.SessionKeyName] ?? string.Empty;
public static void SetValue(SessionKey sessionKey, string sessionValue)
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
cookie = new HttpCookie(cookiePrefix);
cookie.Values[sessionKey.SessionKeyName] = sessionValue;
cookie.Expires = DateTime.Now.AddHours(1);
