Question

I have a small program that hold 4 button in a 2D Array what I want to do is display its ‘X’ and ‘Y’ coordinates of the Array in a message box (when clicked)

I have tried a number of ways some don’t work and some work but I cant get it to show the ‘X’ and ‘Y’ values

The image below shows what I have so far:

And This is the code i have come up with:

namespace _2DArray
{
    public partial class Form1 : Form
    {
        private Button[,] b;
        public Form1()
        {
            InitializeComponent();
            b = new Button[2, 2];
            b = new Button[,] { {button1,button2 }, 
                                {button3, button4}};
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            foreach (Button bt in b)
            {
                bt.Click += new System.EventHandler(this.ClickedButton);
            }

        }
        private void ClickedButton(object sender, EventArgs e)
        {
            Button s = (Button)sender;
            MessageBox.Show("you have clicked button:" + s);
        }
    }
}

Answer 1

try assigning some sort of pointer like give name of the button to keep track of it coordinates

 private void Form1_Load(object sender, EventArgs e)
            { 

                   for (int i = 0; i < 2; i++)
                      {
                         for (int j = 0; j < 2; j++)
                         {
                            b[i, j].Click += new System.EventHandler(this.ClickedButton);
                            b[i, j].Name =i+" "+j;
                          }
                      }
            }
    private void ClickedButton(object sender, EventArgs e)
            {

                Button s = (Button)sender;
                MessageBox.Show("you have clicked button:" + s.Name);
            }
