Save changes prompt
-
Hi everbody, I am developing an ASP.NET application that has many pages. User can move from one to another page by clicking on the navigation bar on the left side of the screen. There is a page where users enter their information. While entering information, if they move to another page, I want the application to display a save changes prompt. Should I use the client side code (e.g JavaScript) or server side code (I see yahoo mail open a new window acts as a prompt)? What is the best way to due with this problem? I have few experiences in developing web-form application. Please advise, thanks. Lan hue sau ai lan hue heo Lan hue sau doi trong heo ngoai tuoi -- modified at 4:16 Sunday 11th September, 2005

In my opinion, to keep it simple you should use some client side code to NOTIFY to the user that it hasn't saved the data, so to force it to click on some 'Save' button; write the instructions somewhere in the page, so the user knows what he's doing. If you're smarter, you can use client side scripts to save the data, but this will fail when the browser doesn't support javascript (or it is disabled: Exploer 6 SP1 usually prevents javascript execution). This tchnique is called AJAX: there are some articles here in Code Project, but it is a little complicated.
