Init Event on tha Page

[andrea rosa]

Hi folks,

I've got a question regarding the managment of the events in a
System.Web.UI.Page.
If I want to write code for this event in my code behind I have to
write something like that:
protected void Page_Init(object sender, EventArgs e)

That works but I don't understand why!!!

How the .Net framework understand that this is the handler of the event
Init?!?!?
For all the others controls I must use the properties windows to set
the right event handler, but I can't do it with the page...
I'm a little confused, someone can help me?
Best

The event handler is hooked-up automatically by ASP.NET since it uses a
particular naming convention. The AutoEventWireup attribute of the @Page
directive controls this behavior:

IIRC you can do that with Pages as well. In the Properties Window select
the Page from the drop-down list at the top. You might not be able to focus
the Page by clicking in the designer, however.

Hi Dave,

Thanks for your reply,

now It's clear how the implicit binding for page events works.

I haven't found it ...but that's not important.[/QUOTE]
