In ASP.NET Page_Load event is raised before btnLogin_Click event.
When the user click on a button it generate a postback (the page is send back to the web server) and there the events are managed in a standard order.
Here is a MSDN link[^] that gives you an overview about ASP.NET Page Life Cycle.

And here is a starting point link[^] for creating and working with ASP.NET projects.
