ASP.NET button not firing event at all-CodePudding

A couple of hours ago I posted a question regarding my code doesn't work, after seeing answers and solutions and try them, my code still not working!

So I tried debugging tricks and tips to see what's going on and I noticed that the problem isn't in my code! It's because the button is not firing an event.

I've tried those solutions and none of them worked:

And then you get this:

Ok, so in above, we created a new web page called WebForm4.

We now have a blank web page, and it will have this markup:
```
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="CSharpWebApp.WebForm4" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
        </div>
    </form>
</body>
</html>
```
Ok, so now we drag drop in a button from the tool box - say like this:

So, we can hit ctrl-s for good measure.

Now, we have this:

Lets drag drop in a text box

So now we have this:

Now double click on button - we are auto jumped to code behind:

We can now enter code for button click event. Say this:
```
public partial class WebForm4 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox1.Text = "Hello World";
    }
}
```
now, f5 to run the page.

And if we click on the button, we get this:

So we assume you followed the above steps. And if not, then follow the above steps and post back what occurs.

So, create a WHOLE new web page - do NOT use any existing page.

Thank you everyone for trying to answering the question.. I spent around 9 hours trying to see what is the problem, when I was checking all the files I saw a js lib code which was preventing the page from postbacking and sending requests, etc.. when I removed it everything worked prefectly.
