Try manually deleteing the AjaxToolkit.dll file from your Bin directory.

I'm working on an Asp.Net project - why is there no TabControl in my VS2017 toolbox? Every resource I've searched just assumes that the control is there.
Based on my research, there is no default tabcontrol in the Toolbox.
You can refer to the following link to know how to create the tabControl in the asp.net webform project.
Tabcontrol in webform
total newbie to AJAX, I got the NuGET an I found the Ajax Control Toolkit
7.1213.0
I ran this PM> Install-Package AjaxControlToolkit
It said successful at the end.
There is nothing to add if I right click a TAB in the toolbox and look in the .NET Framework components.
It says The Ajax Control Toolkit contains more than 40 controls, including... Where do I see them and how do I add them to my WEB page?
I see an 'AJAX Extensions' tab in my Toolbox which was there already, but there are not 40 controls. Just these
Pointer, Scriptmanager, ScriptManagerProxy, Timer, UpdatePanel, UpdatProgress
Are these suppose to be controls I can drag onto my WEB page or how do they work?
First of all you have to take a look at the sample.
Second, you have to download the AJAX-Control-Toolkit and you will find example projects.

Gives me this error on Design View but it works in Code View and in Code-behind.
Wat may be the reason? I have an old .dll of Telerik
I'm using Visual Studio 2010. I havent used any installation of Telerik.
I copy "Telerik.Web.UI.dll" into Bin directory then add reference to my project
I have only 1 dll ("Telerik.Web.UI.dll" ) do I need other dll's as well to be able to work on Design View
I think that you must install Telerik controls to be able to use them in designer.
I don't understand why my AJAX extension controls cannot be dragged into my code. When I drag one of the controls, nothing appear.
I tried to fix this problem by download the Ajax Control Toolkit, extract the AjaxControlToolkit.dll, create a new tab in ToolBox, select Choose Item, select AjaxControlToolkit.dll and press Ok. Then my new tab disappear. Or the tab remains, without any controls in it. However, when I check "Show All", the controls and disappeared tab does exist.
I need to use Ajax in asp.net. Really need help.
Ok I found the solution. My Windows 7 does not have .NET Framework 3.0 which is required by teh AJAX Control Toolkit. After install the .NET Framework in Control Panel->Program->"Turn Windows Features on or off" and changing the project to .NET Framework 3.5, it worked.
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
It sounds that you might have the wrong .Net version of the Ajax toolkit installed. Check http://ajaxcontroltoolkit.codeplex.com/releases/view/43475
I think its a bug and a bogus message that keeps coming time to time with Ajax control toolkit. Sometimes closing the VS and restarting helps. If that does not help, try removing the control toolkit and re-referencing again.
