在ASP.NET中未执行Page_Load

Question

I have this c# code

namespace ZumaApp
{

    public partial class _Default : System.Web.UI.Page
    {
        ServiceReference1.QSLWebBookingSoapClient services;
        public String CallerId = "";
        public Int32 rowCount;
        protected void Page_Load(object sender, EventArgs e)
        {
            CallerId = Request["CallerID"];

and in my asp I have this:

<%@ Page Title="VMP Online Booking" Language="C#" MasterPageFile="~/Site.master"
    AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ZumaApp._Default" %>

My problem

The page load function is not executing.

how did I know that

First: I make a break point on the first line in the Page_Load function, but visual studio doesn't stop at the break point.

second: I make a break point at this line public String CallerId = ""; and Visual studio stops on that line, then I press step over but the page loaded without going to the Page_Load function.

I tried clean and rebuild but dones't help

Try delete the .Designer.cs and recreate it by Convert to web application option.

It can be regenerated by right clicking on the aspx / ascx file and select Convert to web application option.

Some times .Designer.cs wont be refreshed by VS, and need to apply this method to get a fresh .Designer.cs file.

In the InitializeComponent function (which resides in the "Web Form Designer generated code" region), you should have a line which says:

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

This line of code should be automatically generated, and tells the framework to execute the Page_Load function when the page loads. If this line is missing, the Page_Load function won't fire. Adding this line should solve your problem.
