This code has two Labels and two Buttons. The two Labels let you know
whether the Init and Load events were fired. The first button resets the
Labels, and the second Button is used to perform a postback (I simply have
the button invert its BackColor and ForeColors). However, the Init event is
fired every time.

I can't possibly know what you're forgetting
because I don't know what you're doing.
How about posting your code so we can, maybe, help you ?
Reduce the sample to the bare minimum needed, please.

news:%2****************@TK2MSFTNGP10.phx.gbl... That's what I thought, but in all the debugging I have done the Init
event gets fired regardless. The specific test I did was creating two
labels, one of which I modify in the Init, and one that I modify in the
Load. I clear them between postbacks using a Button.Click event handler
and set EnableViewState="false" for the Labels. I also used Visual
Studio's Debug feature, and it showed the code inside Init being executed
on each postback. Maybe I'm doing something wrong in my test, could you
either tell me what I'm forgetting or send me an example? What you said
is what I thought the difference was, but for some reason it isn't
working that way for me. Thanks.

news:%2***************@tk2msftngp13.phx.gbl... Page_Init
The Page_Init event is the first to occur
when an ASP.NET page is executed.
This is where you perform any initialization steps that
you need to set up or create instances of server controls.
You can't access controls in this event because
there is no guarantee that they have been created yet.
Controls are created during this event, and you can control
whether your attempt to use these objects will be denied by
the server processing your request.
The Page_Init event fires only the first time the page is loaded.
When you postback to any page, the Page_Init event doesn't fire.
The Page_Load event fires each time the page loads, postback or not.
Page_Load
This event occurs only when all the objects on the
page have been created and are available for use.

What is the difference between the Page_Init and Page_Load events? When
I was debugging my code, they both seemed to get triggered on every
postback. I am assuming that there is some difference, and I would like
to know what it is so that I can take advantage of it in my code.
Thanks.
