title: Disable dates conditionally with Asp.net Ajax Calendar Extender
body: <p>If you have used <a href="http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/Calendar/Calendar.aspx" rel="nofollow">Calendar Extender</a>, i am looking for ways to disable dates based on selection from another calendar selected date. In a project management application there are end and start dates, i am looking for ways to validate these on client. Someways would require postback which i am not willing to perform. There seems to be StartDate and EndDate properties for the calendar on the server, but does not seem to have any client side counterparts. Have you got any ideas how i can perform this.</p>
