Question

AJAX 'sys' undefined?

Asked by: MarcGraff

I am trying to add AJAX to an existing project but I can not get by a 'Sys' undefined error. It appease that this is a configuration issue but I clearly do not have enough experience with this to figure it out.Any help is much appreciated!

I have referenced the "AJAXExtentionsToolbox.dll" and "AJAXControlToolkit.dll"

Here is my web.config file. I have tryed several solutions without success.

by: MarcGraffPosted on 2008-05-31 at 11:07:55ID: 21684512

UnfortunatelyI do not.

Here is the VB codebehind

Did you install Ajax on the machine on which this app runs? Sys is an Ajax defined type, not a toolbox construct.
If not, did you include the Ajax assemblies (System.Web.Extensions) in your installation (look for them in Gac / bin folder)

by: MarcGraffPosted on 2008-05-31 at 13:50:25ID: 21685036

Thanks for your help so far junges and sjors1309!

Yes, I installed AJAX and added it as a reference. Also, "AJAXExtensionsToolbox.dll" can be found in the BIN folder.

Also, the application compiles without any issue. only when opening the page do I recieve the "SYS" error.

Also, I created an app where I used an UpdatePanel which worked fine but when I tryed to add AJAX to an existing app is where I ran into problems. I looked for some time to find the difference in the 2 apps where I thought the issue could be without success.

by: sjors1309Posted on 2008-06-01 at 03:26:12ID: 21686521

Could you post the exact error message? Could it be that Sys.Debug isn't defined?

by: MarcGraffPosted on 2008-06-01 at 04:56:16ID: 21686683

Sure, here is the message:

----------------------------------------
A Runtime Error has occurred.
Do you with to Debug?

Line: 49
Error: 'Sys' is undefined

What's your setup? VS2005/2008, which .Net Framework version do you target? Which framework for the existing app? The page that you included is a testpage in the existing app?

by: MarcGraffPosted on 2008-06-01 at 05:52:46ID: 21686815

VS 2008, .Net Framework 2.0 is what the app exists in and yes the page "test2.aspx" is within the existing app.

by: sjors1309Posted on 2008-06-01 at 07:21:46ID: 21687231

1. The version of Ajax that you installed onto this server? Is it the .Net 2.0 compatible? System.Web.Extension.dll in default Ajax deployment for VS2008 is version 3.5.x. Same counts for toolbox. Try copying the System.Web.Extensions.dll into bin (remove version info from declaration in web.config)
2. The application that you want to enrich with Ajax. Is it updatable? Did you do a full deployment/publish to test this page, or just copied this page to the webserver?

by: MarcGraffPosted on 2008-06-01 at 08:49:55ID: 21687478

1. Never thought of that. I went into the "bin" directory of my app and it is the dll for version 2.0.

2. I am using my local box. So no, there is no publicaiton yet.

Properties of DLL

by: sjors1309Posted on 2008-06-01 at 11:18:52ID: 21687910

Please check in Solution Explorer the Property Pages for your project. You should get al listing of your references and a Target Framework setting (in category 'Build')

by: MarcGraffPosted on 2008-06-01 at 12:10:30ID: 21688084

The framework is 2.0 and the AJAXExtentionsToolbox is present.

by: sjors1309Posted on 2008-06-01 at 12:25:10ID: 21688148

I'm wondering about System.Web.Extension. This is the primary Ajax Extensions DLL. This is what the toolbox uses. It should be referenced for it's that assembly that contains the base constructs for Ajax. Sys being one of them.
I really think you should investigate in this direction.

by: jungesPosted on 2008-06-02 at 05:42:27ID: 21691423

are you doing some redirections on you Global.asax ?

by: MarcGraffPosted on 2008-06-02 at 08:15:06ID: 21692728

I have a procedure that runs and checks for an active DB session. if is fails, it redirects. I comented everything out in the subs of global.asax.vb but the issue remains.

by: MarcGraffPosted on 2008-06-02 at 08:52:06ID: 21693076

sjors1309, I am not sure where to look. I have added it into my web.config as an assembly and in several other places as you can see from my web.config. I also tried registering at the page level with this without success:

<%@ Register Assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Namespace="System.Web.UI" TagPrefix="asp" %>

I assume that your Gac has System.Web.Extensions installed. But maybe it's the wrong version.
You no doubt have an installation of Ajax (version ASP.Net2) with this dll in it (it's in the installation package) - just try copying the dll into the bin dir of your application before running it.

If you can post the sourcecode of your page (the one that generated the Sys is not defined error) - I mean the HTML markup and a screenshot of the Project properties - References page (grey out lines that you don't want to share)

You don't need to register the assembly in the page. It's registered in your web.Config.

by: jungesPosted on 2008-06-02 at 10:15:17ID: 21693714

in some cases i do the follow:

Start a new Ajax Enabled WebPage project (add all needed references) and add step by step a little part from you project into the new project and try test every time the new project. If the error raise again then you know on what part it is causing.

Junges

If you are using MasterPage then include the follow only on the MasterPage and not include it on the other pages:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

Add the follow on every page
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %>

junges: I added the:
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %>
on the page but I am not yet using any "AjaxControlToolkit" controls.

This resulted in the same 'Sys' error.

I now detect something I didn't see before. You use a trigger but specify a button that's within the updatepanel. Triggers are to my knowledge meant to trigger updatepanels from controls outside of the panel itself. Controls that are inside the panel cause postbacks to occur by default.

You sould remove the trigger, or create another button outside the panel and use it's ID in the trigger declaration

Can you give this a try?

After trying everything I have given up and created a new project in VS 2008. I copyed in the files into the new project and AJAX seams to work fine.
