An example of the different lifecycle events an ASP .NET page goes through

LifeCycleEvents.cs

namespace LifeCycleEvents {
    public partial class Default : System.Web.UI.Page {
        protected void Page_PreInit(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_PreInit");
        }
        protected void Page_Init(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_Init");
        }
        protected void Page_InitComplete(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_InitComplete");
        }
        protected void Page_PreLoad(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_PreLoad");
        }
        protected void Page_Load(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_Load");
        }
        protected void Page_LoadComplete(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_LoadComplete");
        }
        protected void Page_PreRender(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_PreRender");
        }
        protected void Page_SaveStateComplete(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_SaveStateComplete");
        }
        protected void Page_Unload(object sender, EventArgs e) {
            System.Diagnostics.Debug.WriteLine("Page_Unload");
        }
    }
}
