Client side Validators ( for example CustomValidator) work differently in ASP.Net 4.5.
Microsoft calls it Unobtrusive Validation Mode, and they are using jusing jQuery (2.0) for this.
Telerik Controls 2013 Q1 SP2 alre also using using jQuery ( but still version 1.9)
The problem is when using scriptmanager, or RadScriptmanager, after loading the telerik jQuery libraries, client side validators do not work any more. This took me some hours, looking at all kind of possible solutions, but finally the most simple solution is disabling the new functionality by adding a setting in Web.config
So since jQuery looks to be standard in asp.net 4.5 , it would be a good thing if Telerik would use the same libraries.

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