I have downloaded Sample code and run it locally but required field is not working on client side as its working at http://cutesoft.net/example/Validator.aspx 

 

 

I just copied all downloaded content to root folder and by configuring webdirectory i started to use and found its not working and checked to cute soft live example site where it was working fine but today while i was talking to support by chat, RequiredFieldvalidator was not working at live example site also I was surprised! let me know if any kind of configuration is required to make it work.

 

Do needful for the same.
