This 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 am getting this error. I have included my code below.
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Web.UI" %>
<html lang="en">
<head>
<title>Test Page</title>

<form id="Form1" runat="server">

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
Server Error in '/' Application.

Several production websites running for months with no problems, all of sudden now fail to compile sporadically.
The compiler will generate errors:
ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).
On master page code behind files that it did not before.
In addition, this error will go away (most of the time) if we recycle the application pool.
in my asp.net application i am trying to write a file on a network system . i get the above errori have identityimpersonate="true"

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" %>
I have a user control with both an UpdatePanel and a ScriptManager.
Some pages in the system have a ScriptManager of their own, and need to include the UserControl.
This throws the "You can only have 1 ScriptManager" exception.
If I remove UserControl's ScriptManager, I'll get 'UpdatePanel1 requires a Script Manager" exception.
I've tried to modify the UserControl to dynamically include it's own script manager if none exists. But all the methods I've used before involve adding a delegate to Page.OnInit-- which won't work, since the UserControl Init fires first.
Because the system designers here like making my life difficult, I can't create a MasterPage, or a BasePage for the system in inherit off of. I'd be stuck going to each page an adding a ScriptManager before the UserControl on each of them. Is there any way of, in the UserControl, detecting if the page has a ScriptManager, and if not, adding it dynamically in a way that makes the UpdatePanel happy?
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.
Suddenly I got this message:
unhandled exception has occurred. unknown server tag 'asp:ListView'
What can be wrong with the project?
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 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.

-- check remaining/available weight in items table

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.
<%@ Register TagPrefix="cc1" Namespace="AjaxControlToolkit" Assembly="AjaxControlToolkit" %>
when i try to convert this page, its giving me the error. So what could be the work around to fix this issue?

I'm currently migrating a WebForms app over to MVC. One problem I have is that some users will probably have a page like www.mysite.com/login.aspx bookmarked (or maybe some other .aspx page). Currently this will throw an InvalidOperationException stating that the controller 'login.aspx' could not be found. Is there any way I can handle this so that it redirects the user to another page?
I know I can implement Application_Error in the Global.asax file, but I'd rather not redirect on any InvalidOperationException, just when it's an invalid controller.
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
View 2 RepliesI'm taking input from a user and need to stick it into an array, the problem is, I don't know ahead of time how many dimensions the array will have and I also don't know how many items the user will want to stick in each dimension.The array will have a maximum number of dimensions of 4, but an unlimited number of items per dimension.I'm trying to create an unordered html list creator, so I need to know the number of items in each level of the list, and since (As far as I know) you can't create a multi dimensional array with a dynamic size
