Hello Lev,

Could you please take a look at the following forum thread, which should help with the issue you are experiencing:

RadButton and ASP.NET 4.5 Unobtrusive Validation

Most probably, the issue you are facing is related with the validation in .NET 4.5. The easiest way for handling this is to add the following in your web.config file:

<appSettings>

<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

....

</appSettings>

Hope that helps.
