How to set range ?

Well now the control came alive and this is the time to do some modifications:
Firstly  we dont want the user to choose the date late than today aren't  we?
So this code will make it up for us:

$(function() {$('#txtBirthDate').datepick({maxDate: 0},yearRange:('-30:+0'));

});

The code yearRange:('-30:+0') is for make the dropdown years to be 30 years earlier than today
