Confused about writing Page Events in C# ASP.NET

So by default the editor only throws in "protected void Page_Load"
What is the correct way to add in other events.

I had in the past copied the events from other pages where I had
manually typed them in such as:

protected void Page_LoadComplete(object sender, EventArgs e)


So recently I started to skip this ... thinking there was an easier
way... and I started wiring these up in the Page_Load event. Example:

protected void Page_Load(object sender, EventArgs e)
this.Page.LoadComplete += new EventHandler(Page_LoadComplete);

This is great because it throws in all the scaffold-like code that I
But I just noticed today that this causes my Page.LoadComplete method
to be run twice!

What is the proper way to do this stuff in C# ASP.NET 2.0? I know
VB.NET has the nice dropdown at the top that helps you declare the
Page events. What is the right way to do this in C#?

Other than that, you may want to add a IsPostBack control before hooking
the event in Page Load:

protected void Page_Load(object sender, EventArgs e)
if (!Page.IsPostBack)
Page.LoadComplete += new EventHandler(Page_LoadComplete);
It seems like the "Page_LoadComplete executing twice" problem would stem
from having AutoEventWireup set to true and then wiring up the event in page
load too, not from IsPostBack.

Sorry two follow up questions:
Why does "Page_Load" or "Page_LoadComplete" even work without the
wiring (explicitly setting the EventHandler)?
Search help for AutoEventWireup. You will probably find
"AutoEventWireup=true" in your @Page declaration in the .aspx page. You can
set it to "false" to disable the behavior.
How many of these things are "AutoMagically" triggered by the ASP.NET
I believe that it is only Page events.
