title: CalendarExtender Change date with Javascript
body: <p>I have a CalendarExtender control on my page and sometimes have to change the date to the next occuring Sunday. I'm currently using the OnClientDateSelectionChanged property of the control to call a function that will add some days to the date until its Sunday.</p>
  
  <p>The problem I'm having is that if I select a Tuesday in my calendar, the textbox will display the next Sunday but the selected date in the calendar is still Tuesday.</p>
  
  <p>How do I update the CalendarExtender to have the new date that has one I selected in javascript? The textbox the CalendarExtendar is connected to shows the correct date...</p>
