Hi, 
am working with an application in asp.net. In my application have some Telerik controls of version 2012.2.815.40. That application is working fine.

I Upgraded telerik controls to Telerik.web.ui.dll Version 2013.1.417.45 into my application.
When an application is build its getting errors like, 
"The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?)" 

Please tell me the solution as soon as possible

Hi,

When adding a reference to your project be very, very careful that you pick the Telerik.Web.UI that matches your version of your .NET framework.

You could also check if you have the correct version of the DLL in the bin folder of your project and namespace is added on page. Also, remove the old references in the code-behind file as well.

You can find detailed upgrade instructions in this blog post: Upgrade the Version of Your Telerik ASP.NET Controls in 6 Easy Steps.

Hi Rumen Thanks for reply,

How to find whether the Telerik dll new version supports .NET Framework?
I  am working with an application in Visual studio 2012 for web. This application is developed by using Telerik 2012 version in vs.net2010.

In my application I want to upgrade from telerik version 2012.2.815.40 to 2013.1.417.45. when am adding the new dll to my application its getting the above error. How can i resolve this problem? Plz send me the solution.

Hi, 
   I resolved my problem. I have changed  TargetFramework 4.0 to 4.5. Telerik 2013 dll supports .net framework 4.5 only its doesn't support 4.0. so am gettting that type of errors in my application.

Hi,

The Telerik.Web.UI.dll version 2013.1.417 supports .NET 3.5 (2013.1.417.35), 4.0 (2013.1.417.40) and 4.5 (2013.1.417.45). You can find the Telerik.Web.UI.dll assembly compiled against .NET 4.0 inside the Bin40 installation folder as shown in this video: http://screencast.com/t/BsSRtp3IoXB. My suggestion is to use and reference the 2013.1.417.40 version of Telerik.Web.UI inside your .NET 4.0 project.

All the best,

Hello!

I am doing a website project in VS 2010 in .Net framework 4.0. Recently, I have started using telerik contols and used Telerik.Web.UI.dll file 2013.1.417.40 version. I don't have any problem when running it in my local system. But the same project while I am running it on my hosting server, it is showing some error message, i.e. could not load or find the Telerik.Web.UI  assembly.

Need suggestions to solve it! If possible, please reply me with the assembly reference for telerik.web.ui in web.config file.

Thanks,
DK

Hello DK,

I think that the information from this documentation topic will help you eliminate the exception you currently get. Just scroll to the Unknown server tag/Could not load file or assembly errors section and try the suggestions.

Hi,

Currently we are using Telerik.Web.Ui with 2012.3.1205.35 version, and our framework version is 3.5. Now we wanted to upgrade it to the latest version to access latest RadEditor 7.35. So please let us know from where should we get the latest version DLL (plz provide the link) and let us know what steps we need to follow to upgrade it.

Also there are below DLL used in our project, then do we need to upgrade all these DLLs or is it fine if we will upgrade Telerik.Web.UI DLL only?
1. Telerik.Web.Design
2. Telerik.Web.UI
3. Telerik.Web.UI.Skins

Thanks,
Shivlila

Hi,

I am using  Telerik.web.UI.dll of version 2017.1.118.35 and Telerik.web.design.dll of version 2017.1.118.45

I am adding the references of the two dlls to the project.

The target framework I am using is 4.0.

In the Souce mode I am facing the issue "Unrecognized Tagprefix or device filter Telerik" and " Error Creating Control" in Design mode.

Please let me know if there is a version problem of the two dlls and Target Framework

 

Thanks,

Keerthy
