The required field validators and other validators are not working in web server. I test with some small eg., I just printed "Hai" when button click. I have included a required field validator to a textbox. It runs properly in local machine. But when I host it in web server, on button click "Hai" get displayed through there is no text in my textbox. Then the error of field validator is shown. Due to this problem my webpages that connect to database in the application doesn't work properly as the validators doen't work. Please give me some solution.
