Version issues with RadControls

[Rob Venable]

Hi,
I was working away yesterday and got a popup message in Visual Studio saying that there was an update for RadControls so I decided to download it. Everything downloaded correctly but now all of my radcontrols have an "Error Creating Control..." It was looking for a different version but the one that was updated was older than the one I had...so I went back to your site and downloaded the latest trial version and referenced that dll in my app...still nothing. I looked at some of the possible solutions and copied the dll's into the GAC. Now my entire website is down. I like using the controls but I keep having issues like this. How can I get this to work so I can make changes to my controls at design time? I'm using Visual Studio 2008 and Telerik version 2009.3.1314.35.

Thanks
Here is the error I'm getting

I partially fixed it. I removed the dll's from the GAC and now I can at least view my site but I still can't modify the controls through the smart tag. All of my controls have this message.

Hi Martin,
I checked out the link you sent me and I have identified the problem but the solution doesn't help me out. Here is my problem:

Problem:

System.IO.FileLoadException: Could not load file or assembly 'Telerik.Web.UI, Version=xxxx.x.xxx.xx, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxx' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Cause:

There is a reference to a version of Telerik.Web.UI in the web.config that is different from the version of the deployed assembly.

Suggested solution:

Update the reference in the web.config to match the version of the deployed assembly.

This is the problem I'm having. It just doesn't tell me what the reference should look like. I looked it up and found a solution that tells me what the references should be but there are two different solutions. If I registered the dll in the gac then me references should look like this:

<httpHandlers>
      ...
      <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Version=2007.2.1107.0, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
        validate="false" />
      <add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Version=2007.2.1107.0, Culture=neutral, PublicKeyToken=121fae78165ba3d4"
        validate="false" />
</httpHandlers>

but if it is not then my references should look like this:

<httpHandlers>
    ...
    <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI"
 validate="false" />
    <add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI"  validate="false" />
</httpHandlers>

and this is exactly what I have in my web.config. I don't know what else to do. Yesterday it worked and I was able to modify my radgrid in design mode but today I can't and I didn't do anything to the grids or my web.config.
This is frustrating!
Is there anything else I can try?

Hello Rob Venable,

Since the problem still exists I would suggest you to open a formal support ticket and send me the web.config file of your current project. Another option is to send me a stripped runnable demo project that would help me to draw a clearer picture of your scenario.

I thought I'd chime in since this was happening to me as well.  Hopefully it can help others on the same chase...

For me, it happened when I upgraded a project from one version of the controls to a newer version.  Turns out that I had upgraded the project I was working on, but it was referencing the dll from another project that I had NOT yet upgraded.  It was that other dll that was looking for the older version of the Telerik assembly, not the project I was working in.

For what it's worth,
