Rad control not working

[sindhuja]

Hai I had developed a project few months back....using telerik  rad controls. It was working fine. Now i had to modify my project...so when i opened and tried to run my system i am getting following error..\

" Could not load file or assembly RadComboBox.Net2 or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with or it was delay signed but not fully signed with the correct private key. (Exception from HRESULt:0x80131045)

Can anyone help me with this please.

Hello Adriano,

Our suggestion is to delete the Web.UI assembly from your project and insert it again - from the Telerik.Web.UI installation folder.

I got the same problem.
It still didn't work even after i deleted Telerik.Web.UI assembly and inserted it again.
Then I created new project, and copied all files and folders to new project folder.
It run in new project, but my old project still give the same error message.

[Adriano]

Hi!
I solved the problem.
In my case, my project was working correctly in my machine.
But when i started uploading the assembly file "Telerik.Web.UI.dll" to the server, using CuteFTP or Filezilla 3+ i was receiving this error.
I started uploading using Filezilla 2.2.3.2 http://www.filehippo.com/download_filezilla/2512/ and this solves the error.
So, the problem was that the assembly was been corrupted while uploading to the server.

I hope this helps,

Kind regards,

Adrian

Hello Rosi (or admin),

Ok, I am having this problem as well. I tried deleting assembly web.ui (does this mean I need to delete Telerik.Web.UI.dll) from project bin directory?

Now you said, install again from Telerik.Web.UI  folder.

I have only c:\Program Files\telerik\RadControls for ASPNET AJAX Q3 2008\Bin\ folder to install Telerik.Web.UI.dll. (I am using a demo version to evaluate new controls).

I tried uninstalling using gacutil and re installing again. No change effect. Error persists. I am using Net 2.0 and VS 2005 on Win 2000 Prof, Mem 1 GB, with no memory hogging application running during development).

I am totally new  to Telerik controls and literally fighting with no results.

Thanks in advance,
Prashant

Hello Rosi (or admin),

The other Telerik.Web.UI problem went  away. Not sure how, but now I have a new error.
I believe, I have proper entries as per the documentation in web.config, I have added Telerik.Web.UI.dll to the project bin directory.
(FYI - I am using Telerik ASP.NET AJAX lates Q3 08 release).

web.config entries -

<

add assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

 

<

add assembly="Telerik.Web.UI, Version=2008.3.1314.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>

Hello Dennis Valencia,

If you deploy the Telerik.Web.UI.dll in the Bin you do not have to use the full assembly name.

So, please delete this line:

<add assembly="Telerik.Web.UI, Version=2008.3.1314.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4"/>

and changed this line:

<add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI Version=2008.3.1314.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

to this one:

<add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource, Telerik.Web.UI" validate="false"/>

nice solution! thanks so much!

I'm getting the same problem now and it's totally baffling me - but I only see it on one machine.

I've removed and added it back to the project.  However, it works fine when running locally on my PC and on a couple of test servers - it's just happening on one server.  The code and binaries are identical.  Telerik DLLs are in the bin and there are no specific references to versions in the web.config.

[T. Tsonev]

Hi Sphengle,

The case might be that the copy of assembly is corrupt on that particular server. You can use the File Checksum utility by MS to verify that the files are identical.

You can also try putting the assembly in the GAC. The Assembly signatures are verified upon adding them to the GAC.

I hope this helps.

Sincerely yours,
