Would you please provide more details about the exact error you receive? I pre[pared a test demo and tested it with the mentioned 2010.2.826 version of RadControls but unfortunately to no avail - everything is working fine. I attached my demo for your reference, please let me know if I am doing something wrong and instruct me how to reproduce the issue. Once I am able to observe the problem I will do my best to help.
All the best,
the Telerik team
