Hi Suthish Nair Thank you for your reply.Actually I want as below for validating a textbox for date of birth. The conditions are Textbox can't be empty Textbox date should be in format mm/dd/yyyy Textbox date should not be larger than current date. ie; no future date (to show error like -U r not born yet dude)

You can use JavaScript to restrict the year check the key in year and compare with todays date. If equal and greater than today's year then show alert or return false. OnKeyPress/OnChange/OnBlur event of JavaScript will help to validate the entered value.
