• Remember: there is no way to guarantee this code will execute. For example, if the browser executable itself is forcibly stopped (or crashes), or the puter's connection to the internet is broken, or its power cord yanked, etc... In other words, use this technique as a convenience, but NEVER for system-critical code. – mikemanne Commented Oct 12, 2011 at 15:12

You can make ajax request on

window.onbeforeunload = function(){ 
    ////make ajax request
}

Or can prevent the user by giving confirm box

function showalert() {
  if (!confirm('Are you sure you want to exit without saving changes?')) { 
     ////make ajax request
  }
  else {return true;}
}

window.onbeforeunload = function(){ showalert }

For example check this out when I leave this page while answering SO prevent me

Use an ajax post, triggered by window.OnBeforeUnload() to let yourself know that the user has left the page, and pass any information you need.

Well since you want to call the save method even if the user navigates to another page or link what u need to do is set a hidden field for eg. suppose hdnSave and set its value to say 0 Now when the user navigates or clicks on any another link first check if this hidden field value(hdnSave) is set to 1 or not.If not then Call Save Method.So this hidden Field can be used as an indicator of whether Save Method has been called or not.

Similarly you can use a session(in c# code) for the same purpose as well.
