Do you know any cross-browser method to create and save a file with JavaScript on the client-side?
Considerations:
you can do that by Client side Web services just make a function in web service to create a text file in your hard drive then convert the web service in to the client side service when u do that .Net framework make a client side java script then u will be able to call the server side function using Java script in client side after that your file will not be posted in the server it will remain save in your hard drive ok
