[Solved] Old System.Web.Extension required by radcombobox

[Rob Ellis]

Parser Error Message: Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Obviously, after installing 3.5 the version of System.Web.Extensions is now 3.5.0 and 1.0.6... is no longer on my development computer.  Is there a way to override this?

Thanks,

Rob

Hello Rob Ellis,

Yes - you should use the 3.5 build of Telerik.Web.UI.dll. You can find it in the bin35 folder from the  Prometheus installation.

Hi Albert,

I have the correct version of the telerik DLL and solved the view problem in the designer, but the error now says I need v 1.0.6x for System.Web.Extensions.  I don't understand the corrolation between the two so I'm not sure what I should be doing?  I can't run v 1.0.6x and v3.5.0 together.

Hello Rob Ellis,

I have prepared a small project for VS2008. Please download it and give it a try.

I've found the reason for the error thanks to the differences in your project.

When you drag and drop the ComboBox (or any Prometheus control) onto a project it includes the registration line:-

<%

@ Register Assembly="Telerik.Web.UI, Version=2007.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

Your project replaces that line with this :-

<%

@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

If you swap the lines over, then the error doesn't occur.

Now I'm having problems saying that the telerik.web.ui is stored in my local ASP.NET temp files and in the GAC and then crashes! ArgghHh! :-)
