[URGENT] Call Calender (ASP Control) onSelectedValueChange event from ClientSide

Hi all,

I need to call javascript function when date of asp.net control calender is selected.

Actually I am currently using onclick event.. which is not proper for my current use.

Plz URGENT..

One more idea got in my mind to check the statusbar value in javascript.. but i can't understand why statusbar value shows blank when ever i check..

Bec'z when i make mouseover on calender day, it shows value like __doPostBack(.. in Status Bar..

I am using
alert(window.status);

Plz if u get this figure me out..
