I cannot get the value of that Requiredfieldvalidator through document.getelementbyid. It is in content page. Whether that is the problem? It is not working in my project. As it is working in a simple web page.

I think you have master page and that's why you are not getting proper ID, you can try using this...

A:
In ajax control toolkit, there is a control called validator callout that will help you to do this, link here http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ValidatorCallout/ValidatorCallout.aspx

Thank u.. Actually My requirement is when clicking the box, that Validatorcallout should be called. For that I need to trigger it.
