Please go through this: ASP.NET Page Life Cycle Overview
Understanding Page.IsPostBack Property property is also important.
Gets a value that indicates whether the page is being rendered for the first time or is being loaded in response to a postback.
To understand that better, put a breakpoint inside the code written below
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
// excecutes on page load
}
else
{
// executes on button click
}
}
