Required Field validator in Page Layouts

Hi,

I have a Page Layout with few fields which are required , I want to use required field validators on them.

following is one of the TextFields in the Page Layout

<PageFieldTextField:TextField ID="TextField1" FieldName="Title" runat="server"></PageFieldTextField:TextField>

I tried using COntrolToValidate as "TextField1" in my Required Field Validator but that does not work.

if some body can help that would be great.
