Source: DevX An Update on Prompting a User to Save When Leaving an ASP.NET Page 20 Apr 2005 00:00 GMT
Several months ago I wrote an article here on 4Guys titled Using
ASP.NET to Prompt a User to Save When Leaving a Page, which, as its name implies, provides a technique for alerting
a user when they're about to leave a Web page that has "unsaved" data. Specifically, the article looked at using the
onbeforeunload client-side event, which fires whenever a Web page is being exited, be it through the user
closing the browser window, clicking on a bookmark, clicking on a link in the Web page, or any other task that would cause
the Web page to unload.
With some clever client-side programming you can use onbeforeunload to display a modal dialog box whenever
the user is about to leave a page whose content they have changed but have yet to save the changes. This is an especially
handy technique for applications that will be used by people who are not Web-savvy users, and might not realize that they
need to click some sort of Save button in order to save the changes they made.
Over the months since the original article's publication I have received a number of questions from interested readers.
In this article I plan on addressing the two most popular questions: dealing with auto-postback Web controls (such as
DropDownLists or CheckBoxes with their AutoPostBack property set to True); and how to prevent "Unspecified error"
script errors that can creep up depending on how, exactly, the page was unloaded. Read on to learn more!
