I an gating "Unknown server tag 'asp:UpdatePanel'." error in my website. will u please help me to short out this problem,
but while running in local host its wont give error after uploading in to server its give error
so assist me to solve this error.
and also tell that how can I know the version of ajax.
I don't know what is going on. When I try to add a tab container in my page, it allows me to do that but when I modify the code, the unknown server tag error pops up in the design view of the page.
I checked the source code to see if I had my @register clause in there, and it was there, but still the error shows. I don't know what happened, the last time it worked perfectly.
I have also recently downloaded the cute editor for .net and installed the .dlls to my bin folder and it is showing the same simtoms as well.
I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".
I googled the problem and found several ideas :
check if the DLL is in Bin folder check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages check if the DLL is registered in the pages with <% @ Register ... %>
Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?
EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005
I have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind function is triggered while uploading, but after code behind function executed, we are getting this error.

unknown server tag on the design time, and iat runtime it is working properly,
Now, i want use 4 AsyncFileUpload and i added those to page. But three of them in unvisible div tag like

I'm building a dynamic form using XML and XSLT. Anyway I'm using a custom asp.net control for CKEditor, it's an HTML editor.
When I try to add the controls from the XSLT using Page.ParseControl(<the-string-from-the-xslt-here>), I get a warning saying:
Unknown server tag 'FCKeditor.CKEditor'
And of course, if I remove the control from the XSLT everything is working fine and all the regular asp.net controls like TextBox etc get rendered to the string just fine. Does anyone know what I can do about it?
I've recently downloaded Ajax Control Toolkit to use with my ASP.NET web app.I added the AsyncFileUpload control to a web form but when I try to run the application,I get an error :
"Unknown server tag 'cc1:AsyncFileUpload'."
I have this in the ".aspx" page :
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" ?TagPrefix="cc1" %>

View 1 RepliesThis problem is driving me absolutely crazy. I developed a very simple Web part and overrode the CreateChildControls to load a user control. The user control contains a ScriptManager and UpdatePanel from System.Web.Extensions. This Web part appeared to be working fine for weeks and all of a sudden today I get the error:
Unknown server tag 'asp:ScriptManager'.
I keep getting a db parser error. I took it from my text book assignment. Here is the error and code: I am confused with the problem

have a Visual Studio 2010 project which targets v4.0 of the .NET framework.In the project, I have a page with an ASP.NET UpdatePanel - which works perfectly within VS2010's development server.However, when deployed to an IIS 6 server, the controls in the UpdatePanel cause a full-page postback - not an async postback.The site has its own application pool.I've tried visiting the ScriptResource.axd URLs which are present in the rendered page and they all produce valid looking JavaScript files.I can't see any Javascript or other errors.
View 1 RepliesI just upgraded a project which was working fine using some ajax control toolkit components. When upgrading the project from VS2008 to VS2010 now I get an error stating that the 'ToolScriptManager is no a known element'...?My ajaxcontroltoolkit.dll is in the bin folder of the website (as it was before) but that doesn't seem to satisfy the VS2010...
The exact error is:
'ToolScriptManager is not a known element. This can occur if there is a compilation error in the website or the web.config file is missing.
In the build errors I have this error:

Does anyone know what should be done to resolve this...?

Suddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
But I have this reference already.

I am trying to convert a website to a web application project.
while doing that i got some error say:
"Generation of designer file failed: Unknown server tag 'cc1:Rating'"
In my few pages i am using Ajaxcontrol toolkit, so i have registered the tag in the page.

I am currently using a asp.net 2.0 with visual studio 2005.
I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
