[Mono-list] Strange error using Telerik RadControls

Thu Jun 12 03:32:13 EDT 2008

Hello list,
at the moment I am evaluating some commercial controls for the use with 
mono. Although I know the contributers do not officially support Mono, I 
do not want to miss them.
So I tested Telerik's RadControls for ASP.NET AJAX Q1 2008. But I get a 
strange error using the menu bar(RadMenu):

Server Error in '/' Application

Looking at the error I am not quite sure if this a problem with RadControls.
I also have to admit that I am using a Mono version which is compiled 
from the svn (yesterday).

            </Items>
        </telerik:RadMenu>

    </div>
    </form>
</body>
</html>

Does anybody have a hint what the cause of the error is? Is it moreover 
possible to use those controls? An employee of  Telerik told me that 
they are developing a  Mono compatible version and that their 90% of 
their samples are running out of the box, but I cannot share this opinion.

Anyways, I would be glad if somebody could share his experiences with 
that stuff.

Best regards,
