I have a requirement that I have to detect browser close as well as browser tab close.

If a user will click on browser close button or trying to close the tab then I should display a dialog box(has 2 button exit and cancel) that " do you really want to exit " if user clicks on exit then the save its worked data and close the browser.

Thanks

If you want to detect when a tab/window is geting closed. You can do it ,for example on Javascript ,i.e. to detect that kind of stuff are onunload and onbeforeunload events.

Check the following link

Browser/tab close detection using javascript (or any other language)[^]

Here this should be either a javascript or an jquery. It's difficult(but I think there are some possible solutions) to detect on the server side. Bcoz while the time your request is processed , the user might already closed the tab. So to avoid that it is better to use javascript as it could detect the user activity easily.

Solution 2

Follow the article - Save Changes on Close of Browser or When Exiting the Page[^].

You need to use window.onbeforeunload[^] event.

JavaScript

window.onbeforeunload = check;

function check() {
    var response = confirm("Are you sure you want to exit this page?";
    
    if(response == true)
    {
        // Do what ever you want to do. Call function to save data.
    }
}

Refer - Asp.net session on browser close[^] to know how it stores data on browser close by calling a web service.

window.onbeforeunload event get fired every time page get unloaded. So if user will refresh the page or navigate to some other page this event will get fired, so must also handle these scenarios.

Oh nice information. And I believe there is no way to detect the particular browser close button click, isn't it ?

So, how to handle the scenario then ? Is there a way ?

Mahesh Bailwal 22-May-13 3:23am

As per my knowledge you can detect it only by checking the mouse location where user clicked, whether its matching the close button location or not.
Moreover there is no full-proof way of detecting it.

Yes. That may be one way to do this.
