Hello Puleng,

Please follow the instructions bellow:

If you use WebApplication:

1. Open your project in Visual studio.
2. In Solution Explorer navigate to References.
3. Remove Telerik.Web.UI and Telerik.Web.Design from the references.
4. Add Telerik.Web.UI again. Make sure when adding the assembly to point the newest version of the dll.

If you use Web Site:

1. Copy the latest Telerik.Web.UI.dll to the \bin folder of your web site.
2. Open your site in Visual studio.
3. In Solution Explorer, open web.config of your site.
4. Edit references to the telerik's assembly.  Do not use fully qualified name. In <pages><controls> tag, you should have right assembly reference (see the code-snippets bellow).

Instead of:

<add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI,
   Version=2010.2.713.35, Culture=neutral, PublicKeyToken=121FAE78165BA3D4"/>

You should have:

<add tagPrefix="telerik" assembly="Telerik.Web.UI" namespace="Telerik.Web.UI"/>

Kind regards,
Vasil

We are getting the exact same issue.

I've completely removed the 2010.2.713.35 version from the machine.  I've made sure that the version of the dll is the correct verion; check the gac and the old version is not listed.

The problem seems to happen when a radcombo box is populated with data.

here is the error code.  This is really getting frustrating, there doesn't seem to be any logical explanation as to why this old verion is referenced.

I've been doing more experimentation, and here's what's happening.

I delete the telerik reference from the bin directory of the website, removing it from the solution;  I then add a reference to the new 2010.3.1215.35 version of the controls;  go the the bin directory on the file system, it shows that it is the 2010.3.1215.35 version of the dll.

I then rebuild the solution.

If I look at the version of the file in the bin directory, it has revered to the 2010.2.713.35 version, even though it is no longer installed on the system.

What would cause this to revert to an old version, even though the new one should be referenced, and the .refresh file is actually pointing at the new version.

[Dean Killam]

Yet more information.


If I go to Build => rebuild solution, it puts the old 2010.2.713.35 of the dll into the bin directory;  When I click on the debug arrow to launch the site into debug mode, it puts the 2010.3.1215.35 into the bin directory.

Hello Puleng,

I am not sure why different versions are added when build solution and debug it. But you can try to search for Telerik.Web.UI.dll in your hard drive and delete this assemblies with the old version. Check if there are some installed in the GAC as well.

Best wishes,
