Rad Controls Not Rendering in VS2008 Design mode

[Steve]

We recently upgrade to the latest version of ASP.NET Ajax toolkit (v.2008.1.619.20).

When going into the Design mode (for an ASPX page), I am getting control errors.

In one example, I have a telerik:RadAjaxPanel on the page.  The error I am getting is:

"Error Creating Control - panelAjaxPanel
Unable to create type 'telerik:RadAjaxPanel',  Could not laod file or assembly'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicToken=31bf3856ad36e35' or one of its dependencies.  The system cannot find the file specified'.

Any thoughts are what is causing this issue?

Thanks.
Steve

Hi Steve,

Generally when using our .NET 2.0 version you need to have ASP.NET AJAX 1.0 installed. For .NET 3.5 version of our assembly you do not need to install this - the ajax is built-in in the framework.

Kind regards,

Thanks for the quick response.

I pointed to the BIN35 and all is well.

Thanks again.
