AJAX :: Unknown Server Tag Error Even After Assembly Registration?
Sep 17, 2010
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 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.
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'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 have a stored procedure, which I'm calling from ASP.Net application. I'm facing a problem in stored procedure when comparing values.Please check code below to get further details.
Stored Procedure: ALTER PROCEDURE [dbo].[MyStoredProcedure] (@ItemID nvarchar(50), @Weight1 float, @Weight2 float) -- check remaining/available weight in items table DECLARE @RemainingWeight float SET @RemainingWeight = (SELECT RemainingWeight FROM items WHERE ItemID = @ItemID) [code]...
I am getting this error message (in IE) when i click on any of the menu items used in my code, i pasting my code here, please review it and suggest me the corrections, i have tried reading other similar articles which mentioned increasing maxReuestLength(<httpRuntime maxRequestLength="8192" />) but it hasn't solved my problem.
Am getting this error on clicking any of my page link.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0"
As this is registration form, I want server side validation of existing email id .If user entered email id already exist in DB I want to reopen the above modal dialog (automatically) with an error massage Email ID already exist.
In my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50); After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus. Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
I have adeed a dll file on my project and it's working fine with local system. but when i uploaded it on hosting webspace it's displaying error. "assembly refference is missing" i have alreday added bin folder there. So how to add bin folder on hosting spaces.
System.TypeLoadException: Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
I have ajax control toolkit in bin folder ,i have win 7 inmy system but still i m getting this error ..

I have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never" to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.
I have created a server control for my web page... I have decided to add an ajax popup extender (after creating the control, which builds and works fine.) After I add the AjaxControlToolKit reference I add the following:
[Code]....
I get this error when I add it:"The type 'System.Web.UI.ExtenderControl' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Web.Extensions, "I googled the error and it says to add something inside the web config... I do not have a web.configfile inside the server control.
I'm getting this error when I'm trying to run a page that works on other servers. Having trouble finding much info on this error or possible solutions.As far as I can tell, the appicable permissions have all been set, on both the app folders and the framework folders. I've taken all the code out of the page to isolate
I'm using DataContract/DataMembers to serialise my class to JSON for a webservice, and it all works fine, except for one of my members, which could either be class a, or class b, where class b extends class a.
If I omit the KnownType parameter, then an exception is thrown during serialisation:
Type 'ClassB' with data contract name 'ClassB:http://schemas.datacontract.org/2004/07/MyApp.App_Code' is not expected.
As expected, because the ClassB is an extension of Class A, and so not know to the deserialiser. So I need to add a known type attribute, which I do, to the parent Class which contains the member
[KnownType(typeof(ClassB))] [DataContract]
This compiles fine, but the page which I am currently testing this on seems to go bizzare, it loads fine, however apparently the Service doesn't exist anymore, as my JS call tells me and throws and error. But I have no idea why adding the known type attribute on my class causes the webservice to apparently not exist :s
Is it something to do with the fact that my setup is ClassA, ClassB: ClassA, and all the examples I have seen, seem show a ClassA: ParentClass, ClassB: ParentClass setup.
I have a project using Crystal Reports 2008, whenever I try to print the report, using the print button on the menu I get an error on one of my machines, the Crystal Print Dialog opens, completely empty and then I get a error from windows:
Windows has blocked this software because it can't verify the publisher. Name: PrintControl.cab Publisher: Unknown Publisher
This is only happening on my Windows 7 machine. The solution on my Windows XP machine works fine, even if I hit the site under XP from my 7 machine, so I'm assuming something didn't install properly on 7. Any ideas? The 7 machine print dialog comes up blank, just says Print on the title and then the error comes up. The XP machine Print dialog says Print in the title and says Crystal Reports Print Control before the print options come up.
When I am trying to upload a file with more than 5 MB using the file upload control , some unknown error is thrown from the browser. When I tried to diagnose the issue using fiddler it shows 504 error code.
Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"
Note that My Control has,
1) Public property PublicProperty as String
2) 1 Label control
In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).I don't want to register my control using Src, TagPrefix etc.
