How to save Gantt chart then reload it again using ASP.NET

Hi guys:
i need to know the mechanism to save gantt chart into xml file then reload it again through ASP.NET web application .

You can use gantt data like

var xml = gantt.serialize("xml");

which will give you an xml string. Of course you need to save it somewhere during page reloading, if you are targeting relative modern browsers - you can use localStorage API. Save data in localStorage before page reloading, and restore it ( gantt.parse(xml) ) after reloading.
