The only way I can think of is to set some session variable whenever they click a link that takes them out of the page. &nbsp;On unload of the page, check the value of the variable--if they used one of your controls the value could be true...if they used a global function (like back, forward or the 'X') the value could be false.

no way to do this with server-side ASP.... The only way I can think of other than using the JavaScript unload event is the onBeforeUnload event, which is IE 5+ only.

I need to identify whether a page is being unloaded because the X button in the top right hand corner has been clicked rather than the page is being unloaded  because of some other postback event.
How can I do it?

How can I detect that a user has clicked the window close button ?

Active Server Pages (ASP) is Microsoft’s first server-side engine for dynamic web pages. ASP’s support of the Component Object Model (COM) enables it to access and use compiled libraries such as DLLs. It has been superseded by ASP.NET, but will be supported by Internet Information Services (IIS) through at least 2022.
