As of R1 2018 the Telerik.Web.Design.dll is no more added to the GAC during the installation, so you will need to add it manually to the project Bin folder and refer it from there. You can refer the following help article for more details on this matter:

Hello.
This is totally "anti-user-friendliness"... We loose hours searching solutions for those installation issues. I have problems after each new release. The issue is still there with 2018.3.910.45.

This issue has be handled in one of the latest VSX releases (version 2018.1.216.2). Can you upgrade the used Telerik Visual Extensions to the latest version and see if the problem persists?

We are still using Visual Studio 2010 so the new extension will not work. Is there a way around this issue without having to upgrade Visual Studio? The project is referencing the correct version of the file, so I know its not picking them up from the GAC.
Thanks
Can you, please, verify that the all Telerik dlls are taken from one and the same release and are targeting the same .NET version? If this is true, you can see detailed steps on how to update the DLLs manually (without using VSExtentions) in the following help article:

Hello Team,
I am working on RadEditor to integrate trial version with our existing Project VB.Net 4.0 framework.
But when it automatically adds reference in designer.vb the project does not build it says
Error BC30002 Type 'Global.Telerik.Web.UI.RadStyleSheetManager' is not defined.
Please find attached. once we have confirmed that the POC works fine we will upgrade to full version on Talerik.Web.UI
I would suggest that you go through the steps in the following blog post and see if following them will help you to upgrade successfully:

You can also examine the following articles and make sure that all suggested configurations are available in your project:

Hi Vessi,
This is working now, seems incorrect version of Telerik.Web.UI.dll was been referred and expected was 4.0 version
copied from below path in my Machine as i was unable to attach the file due to size limit
C:\Program Files (x86)\Progress\Telerik UI for ASP.NET AJAX R2 2019\Bin40
The POC is fine and we are progressing to formally procurement on RadEditor.
Thank you for the update, Pallavi - I am glad everything is working properly now.
A per the suggested upgrading steps - they are the same both when you upgrade from an older version or from a trial one, so you can use the linked blog as a future reference (if needed).

Error Creating Control - RadMap1Failed to create designer 'Telerik.Web.UI.RadMap, Telerik.Web.UI, Version=2014.3.1209.35,
Telerik.Web.UI, Version=2014.3.1209.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'
Why this Error show Can some one please clear it?
Hi Iaxman,
Such error is usually thrown when there are missing or wrong references to the Telerik.Web.UI.Design.dll. Is the 2014.3.1209 version of the controls the one you are currently using in the application?
Basically, you need to copy the Telerik.Web.Design.dll file with the correct version (e.g., from the installation folder) to the project ~/bin folder and add a reference to it in Visual Studio.
You will also have to ensure that all Telerik DLLs in used in the project have the same version.
More details on this matter are available here:

Virtual Classroom, the free self-paced technical training that gets you up to speed with Telerik and Kendo UI products quickly just got a fresh new look + new and improved content including a brand new Blazor course! Check it out at https://learn.telerik.com/.
I was having the same problem with my update to V 2022.2.511.45
I would have thought that this would have been corrected by now!
So, I did what was suggested for the 2018 version... copied the designer dll from the download folder and placed them in the Bin folder of my project. Closed VS2022 and then opened it back up and now the designer shows the controls.
