Is it possible to call a write a Page_Unload event in code behind similar to Page_Load event? I wanted to call a method on Page Unload. How do I achieve that?

Refer to the ASP.NET page lifecycle to help find the right event to override. It really depends what you want to do. But yes, there is an unload event.

    protected override void OnUnload(EventArgs e)
    {
        base.OnUnload(e);

        // your code
    }

But just remember (from the above link): During the unload stage, the page and its controls have been rendered, so you cannot make further changes to the response stream. If you attempt to call a method such as the Response.Write method, the page will throw an exception.

There is an event Page.Unload. At that moment page is already rendered in HTML and HTML can't be modified. Still, all page objects are available.
