AJAX :: Sys.Extended.UI Is Null Or Not An Object, CombineScripts="true"
Jan 20, 2011
I'm getting frustrated with all this.
In my new webpage version I've added ajax toolkit 4.0 and runing framework 4.0, there seems to be some problems with the ToolScriptManager CombineScripts.
I have a MasterPage that all pages derives from and in this MasterPage I have a ToolKitScriptManager with LoadScript.....="false" CombineScripts="true". In my masterpage I've added a ModalPopUpExtender
When I start the webpage I can't show ModalPopUp (www.url.com) but if I go to any other page it works ex. (www.url.com/testpage/), if I disable CombineScripts="false" the the starting page works but then I get so many more httprequests.
Iam using AJAX HTML Editor in my project. Initially i made the HTML Editor as invisible and if i click on the button the HTML Editor shoud be visible but when i click on the button iam getting this errorr "Sys.Extended.UI.HTMLEditor.Editor is null or not an object".
If i allow all users to access this folder or remove this web.config file, then the ajax toolkit works. I need to protect this folder and i am using form authentication. Could someone point me where i went wrong. Kindly keep in mind that i am new to asp.net.
I decided to use the CalendarExtender on a project and I converted it from VS 2005 to Web Developer 2010 Express. I initially added the AJAX toolkit for ASP.NET 4.0 and the calendar extender worked fine. However, I realised that the server didn't have ASP.NET 4.0 installed and I thought it would be simpler to add the toolkit for 3.5 instead and change the target framework to 3.5. I tried and then the CalendarExtender did't work at all. When you click the textbox nothing happens. There is the error on page - 'sys.extended.ui.textboxwrapper is null or not an object'
I tried switching the project back to 4.0 and using the other one and that no longer works for some reason. The same in 2008 Web Developer Express. I've clearly done something wrong along the way, but I can't work out what it is.
Here's the source for a page on a test Web Developer 2008 Express project.
i am using urlrewritingnet for url rewriting. at one of my page i am using auto complete extender . it works fine for first page weirdly because also that page is getting url rewriting.
now let me explain you
my normal page is
domain/Pokedex.aspx
here what i do for url rewriting
[Code]....
ok now problem does not happen when i type this : domain/Pokedex.aspx. but i when i type this problem occurs : domain/Pokedex-2 which is equal to domain/Pokedex.aspx?page=2. here is the problem screen shot but when i type this problem does not happen : domain/Pokedex.aspx?page=2 so it is about url rewriting i guess
This works fine but from a performance standpoint this is not good as the pages are making a lot of requests to the webresources.axd and scriptresource.axd files. When I changed the CombineScripts property to true my ASP.NET AJAX control extenders are no longer working. What is the reason for this weired behavior and is there a fix for this?
I have a collapsible panel on my page that has been working up until yesterday. I have no idea what changed, however, it is no giving me the following error.
Microsoft Jscript runtime error: 'Sys.Extended.UI' is null or not an object.
Below is the code for the Collapsible Panel, however, I don't think it has anything to do with it since it has always been working.
I'm using a ScriptManager and including a webservice in the script generation. Upon calling the web service method via the javascript, I get the expected response except in IE 7/8. I get the error 'undefined' is null or not an object. I do not get this error in FireFox, Chrome and even Safari. The catch is, this is Microsoft's own generated code coming from the generated code from the script manager! This is the code that the error is thrown on:
I am getting following error "sys.webforms.pagerequestmanager is null or not an object" in my login page.login page contains script manager tag at start and Ajax CollapsiblePanelExtender n page.
I recently converted my VS 2005 project code to VS 2008.My old code is running fine.
in my application for a module that displays detailed data in a tab control. I think I have determined the TabContainer1 is the name of the "This" element that is having the issue. I figured this out by debugging the ScriptResource.axd file. Here is the offending lines of code:
[Code]....
The way the app works is there are two modules that work together on the page. One is a selection grid and the other the detail form which shows the details from the selected item in the selection grid. If a user is in a limited role they can only see the data of the default selection and they do not see the grid to select from. It is under this circumstance that I get the error and the detailed module is not rendered. However if I break the code and skip over line 139 to line 140 the detailed information shows correctly. Otherwise I do not even see the detailed form. Based on that I know the detail form is working correctly but is not rendered after this error occurs. In addition I am using this same logic with another detailed pain that works correctly under both roles.
I can not seem to narrow in on any code that is causing the issue. For one thing I have no idea as to where the ScriptResource.axd is created. I also do not see where there is any settings for the tab control for submitions and I am not able to find an "OnSubmitStatements" in my code.
Ik keep getting this sort of errors when using Ajax controls.The colorpicker extender and the Cascaded dropdown generate this kind of error in my application.I have a scriptmanager in my masterpage.I already tried using a scriptmanager proxy.What could cause these errors?I have the controls inside template fields of data presentation controls.
While testing an AJAX enabled web app I sometimes stumbled upon this script error: 'this.get_element().style' is null or not an object. It was a hard nut to crack this one.This was the actual message
'this.get_element() is null or not an object'
The situation:AJAX Enabled web app using slider extenders . In some circumstances a script error is generated. In most cases it is not.
The reason:It turned out that the error happens at times when a new Postback is triggered while a previous one hasnt finished yet. That is quickly changing the sliderhandle's position in this scenario. The Postback where triggered because i had set the AutoPostBack property of the extended TextBox to "true".I have some code running inside the event handler
I am getting "Sys.webforms.pagerequestmanager is null or not an object" error when calling the webpage from outlook for some client machines. In some machines it is working fine.
I am using some AJAX and some JQuery for Login panel animation in Master page.Also in my home page I am using AJAX Tab container.It works fine when I run the application without login.If I logged in I got the following error when I put the breakpoint into my code,
Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object,It shows at the following Line at the Home[dynamic] page.
I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'Sys.Extended.UI.AccordionBehavior' cannot be converted to type 'Sys.UI.Behavior'. Parameter name: instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010 ASP.NET 4.0 Ajax control toolkit 4.0 jQuery 1.4.2 jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function() { var c=this; b.UI.Behavior.callBaseMethod(c,eb); --------- this line var d=c._element; if(d) { var f=c.get_name(); if(f) d[f]=a; var e=d._behaviors; Array.remove(e,c); if(!e.length) d._behaviors=a; delete c._element } }
*Update: * Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?
this code give that solution.but if any one of the field have null(example:r.urrQuickLinkRights contain the NULL) then only it will throw error like Object reference not set to an instance of an object.
We just upgraded from 2.0 to 3.5 and the latest AJAX Toolkit. AjaxControlToolkit.dll is version 3.5.40412.0
Project references are up to date. The old Toolkit files were deleted and the new ones copied from the distribution ZIP. ScriptManagers were replaced with ToolkitScriptManagers. The project builds with zero errors. The built-in AJAX controls (UpdatePanels, etc.,) work but the Toolkit controls don't. This is happening on local developer boxes and on our development server.
The javascript error we're seeing is "Sys.Extended is undefined." It's occurring in server-generated script blocks like this:
I have a simple method which takes an Object and return string "No" or "Yes". Basically I want to display "Yes" or "No" when a bool value of 0 or 1 is there
But everytime there is a 1 passed to the CheckValue which in the debug shows as true, It never evaluates being equal to "true" what am I doing wrong? My Checkvalue is always returning "No" no matter what I pass.
I have an load of images on my form with the purpose that if the user holds the mouse on it, (s)he gets a tooltip with some information. The image is a questionmark.The users are now asking if the duration of this tooltip can be extended so they actually can read all of the tekst.So it would be great if a TooltipExtender could be created that can be connected to a image control (or any other)
