Page_Load fires twice with submit on asp:login

Why is my Page_Load called twice? I'm using VS 2008 and I see this when I put a break on Page_Load and step through it. First time isPostback is true, second time it's false.

Here's my aspx page:
-------------------------------

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="STN.test" %>

<head  runat="server">
    <title></title>
</head>
<body>
    <form id="form1"  runat="server">
    <div>
        <asp:LoginView ID="LoginView2" runat="server">
            <anonymoustemplate>
                <asp:Login ID="Login" runat="server">
                
            </anonymoustemplate>
            <loggedintemplate>
                <div>
                    LoggedInTemplate
                </div>
            </loggedintemplate>
        
    </div>
    </form>
</body>
</html>

Here's my aspx.cs page:
-------------------------------

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace STN
{
    public partial class test : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

Solution 1

Pages do not fire, but events can.
Do you mean each of Load and PreInit fires twice? You don't any event handlers added to event invocation lists (where this code is, either in code-behind of ASP XML?), but you can add them twice or add different handles to the same event.

As mentioned, the PreInit and PageLoad in both default.aspx and my masterpage file fire twice.

Sergey Alexandrovich Kryukov 25-Apr-11 21:33pm

Thank you for confirmation... Hm. Did you check up what I suggest?

There is nothing else involved, page works fine until the submit on the Login.

The first time through my default page isPostBack is true, second time it's false.

Sergey Alexandrovich Kryukov 26-Apr-11 1:01am

Again, nothing else can be told based on the code you show.

You did not show the code where Page_Load and Page_PreInit are used. Where is it? All issue is around it, why didn't you show it?

Maybe if you show it the problem will be clear.

I removed all the code from Page_Load and Page_PreInit to test, still had the same problem.

Sergey Alexandrovich Kryukov 26-Apr-11 1:11am

Of course, what difference would it make?!
You need to show the code ***using*** Page_Load and Page_PreInit, post it using "Improve question". is it possible.

Please understand, without looking at this code nothing can be said...

It seems we have a communication gap. I have removed all code except the ASP:LOGIN. There is no masterpage, no Pre_Init. Still, Page_Load is called twice. Here's ALL the code for my test.aspx page:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="STN.test" %>

<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:LoginView ID="LoginView2" runat="server">
<anonymoustemplate>
<asp:Login ID="Login" runat="server">

<loggedintemplate>
<div>
LoggedInTemplate
</div>

</div>
</form>
</body>
</html>

Here is the test.aspx.cs page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace STN
{
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
}
}

No! If you just declare Page_Load, nothing will call it (not even once :-)! How come you don't understand it.
If should be somewhere. Do global search and find it, C# or XAML. Period.

Wrong, AutoEventWireup set to true causes Page_Load. And AutoEventWireup is my problem

Sergey Alexandrovich Kryukov 26-Apr-11 11:11am

I see, thank you.
Now, can you dump a stack on each fire and log it to see what happens in each fire.
If you use Stack, it will show you from where each call came...

Solution 2

AutoEventWireup="true" causes this.
