IIS Configuration :: Unknown Server Tag - ControlParameters
Feb 24, 2013
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.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Unknown server tag 'asp:ControlParameters'.
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:
I have a web site project. My project contains two files Web.config. One. The configuration file in the root directory, the second child in the directory(see below).All pages in the root directory work fine, but all the pages from the catalog of the child doesn't working. I receive error "Unknown server tag ''Compon##:Calendar""
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.
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 :
I am trying to capture some user input and add it into a database. Here is what I have: { CreatePost.aspx }IMG]http://i56.tinypic.com/n2ijgz.jpg[/IMG]And here is my code in the code behind file { CreatePost.aspx.cs }:
[Code]....
I have also went ahead with PeteNet's advice and added this to my web.config:
[Code]....
However I am still getting that famous error:A potentially dangerous Request.Form value was detected from the client (ctl00$content$txtBody="<p>Hello. This is ju...").I would greatly appreciate any help in sorting this error out.
As you can see there is a ControlParameter bound to a TextBox on the aspx page. So the content of this TextBox is a parameter for my SelectMethod. But there is a special button on the page: When this button is clicked and a postback occurs I don't want that the DataSource extracts the content of the TextBox to control the selection, instead I want to set a specific hard value "x" as the selection parameter.
How can I do that? Can I "disable" in some way the ControlParameter when this specific button is clicked and set my special value instead? Or is there any other way?
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 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 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 have two DropDownLists, and each one has a Control Parameter that references the other.
The idea is that if you select a value in either one of them, it restricts the possible values you can select in the other. And the user may select either one of them first.
Each one has an "All" option for selecting all values. (They are both used to restrict rows that populate a GridView).
This is all done using SQLDataSources.
The problem is that it doesn't seem to work at all. Both DropDownLists are empty, and the SQL that populates them never hits the SQL Server. But there is no error displayed.
If I have it going only one way, it does work, so I think the problem is the recursive nature of having them reference each other.
It would seem to be quite a common requirement, so its there any way of getting this to work?
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"
I was configured an application in IIS,while running it shows login page successfully and i entered the credentials then it was redirected to HomePage with an error of(HomePage not displayed but the URL is rediredcted to HomePage)
Error message 401.2.: Unauthorized: Logon failed due to server configuration.Already i was searched in google and tried to resolve the problem but no use.
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.
