ASP.NET Validator Scripts Missing

For some reason, on some of my pages, the default validator script isn't rendering with the page. The reason makes sense; I'm using the Telerik 开发者_运维百科RadAjaxPanel, which scenario-wise I could just also say UpdatePanel. The panel wraps the pages and AJAXifies the responses. Initially, the controls do not have a validator on the page, and thus, the validation scripts are missing.

Regardless of the reason, is there a way to render the Validation script manually with the ScriptManager? Is this embedded in the System.Web DLL?

Thanks.

I ended up adding a hidden control/validator in the master page, and then this issue went away. HTH someone.
