Question

Page_Load executing twice, even with AutoEventWireup settings

Asked by: krapvag

Hi,

I have an aspx page that fires the page_load event twice.  I've implemented AutoEventWireup=false in the page directive, and the cs file looks as below in the code box

I've stepped through the code, line by line, but the as soon as the page load event finishes, there is a delay and the Page_Load event is being fired again.

Is there any way I can check to see if something is making it call the page twice?  I have looked in the IIS server logs, and there are two GET requests about 10 seconds apart for the same page.

Or is it something I am missing in the code below?  Thanks

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage2.master" AutoEventWireup="false"
    CodeFile="ProjectDetailsView.aspx.cs" Inherits="EventWireUpFalse" %>
 
public partial class EventWireUpFalse : System.Web.UI.Page
{
    override protected void OnInit(EventArgs e)
    {
        this.Load += new System.EventHandler(this.Page_Load);
    }	
 
 
    protected void Page_Load(object sender, EventArgs e)
    {
    }
}

Just blind guesses:
If you have something like
<meta http-equiv="refresh" content="10" />
in the header of the web page it will just refresh it 10 second after the page load.
Also it is possible that there is some java script which is reloading the page after it is loaded.
I suggest to look at the HTML generated by this web page and search for "something" which can reload the web page.(like mentioned above META header or JS).

If you get two get requests then it would execute twice. You are adding the load event in oninit so that makes it execute once per request. Are you doing any redirects to the page? Have you tried using another client?

Interesting, initially I was testing this using FireFox, however I've just used IE, and it only ran the Page_Load event once

The page itself is reached by a HyperLinkField in a gridview

The site uses windows authentication, do you think that could be anything to do with it?
