Getting date into a label every time the date is changed

I am using this datetimepicker by Trent Richardson, I can get the date time picker to work, however after the date is changed i need it to be put into a hidden asp.net control that is in an upda开发者_如何学JAVAte panel.

So how can i make it so everytime the user changes the date and time it is sent to a label.

So since it seems like it's just a extension of the jQuery ui datepicker, you could use the altField option: http://jqueryui.com/demos/datepicker/#alt-field

or the onSelect Event to do it yourself: http://jqueryui.com/demos/datepicker/#event-onSelect
