very weird problem

I have installed lastest ajax and also toolkit too. I created master page and default aspx page, then I put my scriptmanager inside the master page and update panel inside the default page, I didn't choose ajax enable website because I have a hard time to place my existing web.config files, assemblies, connection strings to right place of the enable ajax's web.config file. Maybe I should though, with this error.

I get errors sometimes with all the controls in update panel, is not recognized my html tag, even though my controls are declared, it says it is not, But it builds application suscessfully. I made sure I put this

<%@dotnet.itags.org.RegisterAssembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"Namespace="System.Web.UI"TagPrefix="asp" %>

to my page and also in web.config file under config section also assemblies too. Thing is I think every time I backup my website to my documents, for some reason a while later this happens. I even reset my iis to clear my temp folder of asp.net too. Still. Why this is happening ?

You'll also need an reference to the following assemblies:

- AjaxToolKit.dll
- System.Web.Extensions.dll

You can do this using right click on your project, "Add Reference" and point to this DLL's

On bin folder, I have got these ar, cs, de, es, fr,he,hi,it,ja,ko,nl,pt, ru,tr-TR,zh-CHS, zh_CHT all
thas AjaxControlToolkit.resources.dll in it.
Then AJaxCotrolKit.dll under neat AjaxControlKit.dll.refresh and AjaxControlKit.pdb

Microsoft.Web.UI.WebControls.dll with Microsoft.Web.UI.WebControls.dll.refresh

I have these dll on my bin now, and still problem

I had these dll on program file but not pointing to my project. I am right clicking my project and add references, choosing these dll and adding but it is not showing under my bin folder for some reason, can someone tell me steps to how to add these dlls to my projects.

Is anybody didn't have this problem? I go crazy here with this..

this was nothing to do with ajax, it was copy paste problem..

Visual Studio wont recognize some AJAX components when there is a master page

This is a really weird thing. I have installed AJAX and the toolkits and the validators, and everything was working fine. Then, suddenly, Visual Studio won't let me switch to design view b/c the script Manager and the update panels are now "not known elements," and so are all the labels, panels, dropdownlists, etc inside the update panels. Oddly enough, the components in the AJAX toolkit are still recognized just fine. when this problem first started happening, i would click over to the master page and click back to the aspx page and everything was fine. Now that doesn't even work. And the craziest part is that the web site runs just fine when I debug it, AJAX functionality and all!

I would have blamed this on the way I installed the AJAX framework, but this only happens on pages with master pages.

Does anyone have any experience with this? Or is it just my machine? No one else here at work is having this problem, but I am the only one who is really using AJAX.

Any ideas would be welcome. Thanks in advance

Hi,

As far as I know, the error message indicates the issue is related to permission. It seems your ASP.NET applications run in partial trust. This is configured through the <trust level="xxx" /> setting in web.config or machine.config. Please change the "xxx" to medium and try again to figure out whether the problem still occurs.

Best Regards

Thanks for your suggestion. I don't even have any trust level permissions in my web.config files, so I am assuming that the problem is in my machine.config file. But before I go messing around in there, I would like to try to override it in the web.config. This is what I have in my web.config. But the error I am getting on the page declaration of the default.aspx page is "Unable to read the security policy file for trust level 'medium'." Where are the policy files located?

<location allowOverride="false">
<system.web>
<securityPolicy>
<trustLevel name="Full" policyFile="internal"/>
<trustLevel name="High" policyFile="web_hightrust.config"/>
<trustLevel name="Medium" policyFile="web_mediumtrust.config"/>
<trustLevel name="Low" policyFile="web_lowtrust.config"/>
<trustLevel name="Minimal" policyFile="web_minimaltrust.config"/>
</securityPolicy>
<trust level="medium" originUrl=""/>
</system.web>
</location>

VS 2005 and intellisense

Hi there.

I seems that when it comes to intellisense, VS 2005does not seem to cope with the AJAX tags when used from a page thatinherits from a master page. For instance, take this basic page:

<%@dotnet.itags.org. Page Language="VB" MasterPageFile="~/Master.master"AutoEventWireup="false" CodeFile="Test2.aspx.vb" Inherits="Test2"title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true">
</asp:ScriptManager>
</asp:Content

The openining "ScriptManager" is underlined in red for me as an unknownelement. I'm using VS 2005 Team Edition with the latest Beta downloadof the AJAX library. Can anyone help?

Cheers,

Mike

Just to let you know that you are not alone. I have the same problem.

Same here. I didn't realize it was the master page that was causing this problem for me though. Thanks for pointing it out.

Find the following section in the web.config file:

<pages><controls><add tagPrefix="asp" namespace="Microsoft.Web.UI" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/><add tagPrefix="asp" namespace="Microsoft.Web.UI.Controls" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/></controls></pages>

change it to

<pages><controls><add tagPrefix="msajax" namespace="Microsoft.Web.UI" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/><add tagPrefix="msajax" namespace="Microsoft.Web.UI.Controls" assembly="Microsoft.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/></controls></pages>

You can choose your own tag prefix, just dont' use 'asp' as a prefix. Next you must change the prefix for things like update panel to your chosen tag prefix.

wow... thanks for this!

Hi, it is a stupid problem in the all versions of VS Studion 2005. We had some discussions with guys from Microsoft, but without any results... If you use some master in the your page, and Intellisense doesn't work - just open required master page in the VS Studio, switch back to the your page and - all will be Ok...
