If a user closes out of Internet Explorer by using the X in the top right corner, how can I prompt the user and ask them if they want to save or cancel the transaction? &nbsp;If they want to save, I need to call a C# SaveValues() method, if they want to cancel, I need to call a C# RollBack() method. &nbsp;Is this possible? Do I need a pop up? &nbsp;I read dont use popups, because pop up blockers will cause them not to load.<br />
<br />
Whats the best solution using asp.net 1.1, c#, javascript...<br />
<br />
Thanks!<br />

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
