winforms - C# Windows Forms code not working - Attach Event to button

Question

Could someone explain the reason why the code below does not work?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Speaker
{    public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {

    }

    private void button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show("bravo you did it");
    }
}
}

The window I have designed that corresponds to this code is a single window with a single button. I have the intention to do quite an extented program, but encountering problems, I decided to start with a small sample to see what's wrong, and I see neither this simple code works. Any suggestions? When I press the button1, nothing happens at all.

Answer 1

Make sure attached the event Click with your button. You can do it by going to designer, double click the button, it will create the event handler for you in the code. You can also attach the event handler in your Form Constructor like:

public Form1()
{
    InitializeComponent();
    button1.Click += button1_Click;
}

You can go to the designer, right click on Button1, click properties, Got to events and there you can attach the event handler:
