Could not load file or assembly

[Aewin]

Dear Telerik Team,


Please do me favor one thing.

Now,I'm facing the  following error.

Could not load file or assembly 'Telerik.Web.UI, Version=2011.1.413.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2011.1.413.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

Thanks in advance....

Hello Telerik Team,

I need to know answer urgent.You have not yet replied after two days I asked..

After I changed Telerik licensed dll,that error comes out.

Which assembly version should I need to change???

[Bartholomeo Rocca]

Hello Aewin,

If you are upgrading from 2011.1.413.40 to latest, you will probably need to update the version in the handler registration as well:

<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2011.2 712.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>


Greetings,

Hello Bart,

There's still have error and when I tried the following one,it does work.But I'm not sure it's the correct way or not.
 <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />

Anyway,Thanks for your reply.

Hello Aewin,

Can you post your web.config here? Have you updated both http handlers in the system.web and the system.webServer sections there? Check this help article for more info: http://www.telerik.com/help/aspnet-ajax/introduction-registering-the-httphandlers-on-windows-vista-iis-7-integrated-mode.html.

Hello Aewin ,

We reviewed the attached web.config files and we were able to correctly load the chart with the first one as soon as we added the necessary http handler registration in the webServer section of the web.config (see the attached sample application and the help topic Bart mentioned here).

As for the rest of your web.config snippets -- it seems there is a missing dot (".") in the version string (Version=2011.2.712.40) and probably this triggers the more cryptic errors.


Kind regards,
Giuseppe

I had the same error message and finally found my solution. I decided to post it here, knowing it's not the perfect place. But it may still help someone with the same situation.

I use radgrid, and after upgrading it, it still worked on my deploy machine, but no longer in the test environment!
After a LONG time of searching and implementing many suggestions, I found that on my productive/test environment, IIS7 was running in Classic mode. Switching it to Integrated and my "RadGrid-Portal" worked immediately.
