tELERIK [A] ASSEMBLY PROBLEM

[Ayesha]

Hi,

As i'm getting weird design errors , telling cannot load assembly, cannot generate designer,
telerik[a] cannot be cast into telerik[b].
 So,I deleted some telerik.web.ui.dll , copied from somewhere. but no use. i read many blogs for 2 days and I'm really tired of trying anything. My project deadline is very close.

Can i go ahead and delete my radcontrols at( c:/programfiles/telerik/RadControls for ASP.NET AJAX ....
and  download them again. because i think that my help me .

But if i delete all  references and download the trial version in my system with the latest release now, will it solve my problem

Note: many ppl are in my project and they all have the old assembly refernce telerik.web.ui.dll version 2009.1.402.35.
The project has reference pointing to this 402.35 version. so , what may help my problem. I'm clueless. pls help me asap .

Should my colleagues too change therir refernce to my new reference or shall them have the  old refernce.
We're using the trial version.
Thanks,
ZR,

Hello Zaheka,

I recommend you try the following steps:

DELETE THE TEMPORARY FILES
1. Close your Visual Studio and then delete the whole contents of the folders listed below

Windows XP:

• C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
• C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies\
• C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Microsoft\VisualStudio\8.0\ProjectAssemblies\
• C:\Documents and Settings\%USERNAME%\VSWebCache

Windows Vista:

• C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
• C:\Users\%USERNAME%\AppData\Local\Microsoft\VisualStudio\8.0
• C:\Users\%USERNAME%\AppData\Local\Microsoft\VisualStudio\9.0
• C:\Users\%USERNAME%\VSWebCache

USE FULLY QUALIFIED NAMES TO AVOID CONFLICTS WITH OTHER VERSIONS
web.config:

<controls>
   <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
   <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
   <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121FAE78165BA3D4"/>
</controls>

AS?X Page / Register directive:

<%@ Register Assembly="Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121FAE78165BA3D4" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

Additionally I suggest you examine the links shown below:

Hope this helps.

What are the directories for Windows 7?

[Konrad]

Folders for Windows 7 will be the same as Vista.

Windows Vista:

• C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
• C:\Users\%USERNAME%\AppData\Local\Microsoft\VisualStudio\8.0
• C:\Users\%USERNAME%\AppData\Local\Microsoft\VisualStudio\9.0
• C:\Users\%USERNAME%\VSWebCache

Oh, I had "Don't show hidden files, folders or drives" in the Tools | Folder Options . My bad.
