ASP.NET page_init event?

Question

I am using ASP.NET 3.5 and i used earlier 1.1 i am having difficulty to find where can i attach/declare the page init event ?

In 1.1 there was auto generated code which used to have initialization code. Where we can add the page init method. So i am confused please help.

ASP.NET 2.0 changed the default designing/compilation model.

By default AutoEventWireup is set to true, which instructs compiler to automatically attach event handlers from the code behind using naming convention, so when you write:

protected void Page_Load(...)
{

}

it automatically puts this code in behind the scenes:

this.Load += new EventHandler(this.Page_Load)

This was previously done by InitialiseComponent() (i believe).

Nonetheless, the answer is to write the code yourself:

protected void Page_Init(object sender, EventArgs e)
{
    // do the bartman
}

The only problem is that there is no autocomplete available on this. You have to know exact syntax of the event handler. — FrenkyB, May 13 '17 at 06:12

Just declare this in your code behind:

protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
    }

But for event attachment we need to do something like page.OnInit += evnetHnaglerName(Sender, EventArgs) where is that declared ... ? that is where i am more confused. – Anil Namde Nov 02 '10 at 10:57
no, because you are overriding the method. This is all taken care of for you. – kemiller2002 Nov 02 '10 at 10:58

It's not like 1.1 where you can see the code. They've hidden a lot of it in the other part of the partial class. – kemiller2002 Nov 02 '10 at 11:00

You don't have to bind the event. Just create an event handler for it, and it will be bound automaticlaly:

protected void Page_Init(object sender, EventArgs e) {
  ...
}

For those using asp/vb.net you need to declare in code behind as: Protected Sub Page_Init(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Init

you can add the page_init method in page's CS file. For example, if you have Default.aspx you can put the method in Default.aspx.cs

When you create a page in VS you will have the Page_Load method created for you. You can put your page_init code & other code for the page int the CS file.

PS: If you use VB as the server side code, you will have to put it in the VB file

It is no different in ASP.NET 3.5 - there is a code-behind page where you can declare/attach the OnInit event.

To see the code behind, right click on the file in the solution explorer and select View code.

}
