Partial call back from Ajax Extender Calender date changes

Partial call back from Ajax Extender Calender date changes

I am using the ajaxToolkit:CalendarExtender control. I want to call a
server method after the date has changed. I am currently using:
OnClientDateSelectionChanged="function
ddd(){__doPostBack('DateTextBox','') ;}"
This will do a partial post back in IE but in Chrome it will do a full
post back. I have thought of calling a jquery method for the
OnClientDateSelectionChanged event. I have failed on an .Ajax call but on
a Post back call it does a partial callback. But, i do not get a chance to
select a date. Using this jquery bypasses the chance to select a date. Any
advice would be great.
thanks
