So, I'm attempting to create a grid on the screen, and to do so, I've implemented a multidimensional array of Rectangles. 

When the program starts, I use a for loop to increase the x and y coordinates to form the grid.
public Form1() {
    InitializeComponent();

    for (int x = 0; x < 12; x++) {
        for (int y = 0; y < 12; y++) {
            recArray[x, y] = new Rectangle(y * 50, x * 50, 100, 100);
        }

        Application.DoEvents();
    }
}


My issue is trying to figure out when the user has clicked on a rectangle, and furthermore, which rectangle in the array that he/she has clicked on. As I will change the border to red when given the correct rectangle.

I'm using Visual Studio 2008, and here is my code so far.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Quoridor {
    public partial class Form1 : Form {
        Rectangle rect = new Rectangle();

        private Pen pen = Pens.Black;

        Rectangle[,] recArray = new Rectangle[12, 12];

        public Form1() {
            InitializeComponent();

            for (int x = 0; x < 12; x++) {
                for (int y = 0; y < 12; y++) {
                    recArray[x, y] = new Rectangle(y * 50, x * 50, 100, 100);
                }

                Application.DoEvents();
            }
        }

        protected override void OnPaint(PaintEventArgs e) {
            base.OnPaint(e);

            rect.Location = new Point(2, 2);

            rect.Size = new Size(100, 100);

            for (int x = 0; x < 12; x++) {
                for (int y = 0; y < 12; y++) {
                    e.Graphics.DrawRectangle(pen, recArray[x, y]);

                    Application.DoEvents();
                }
            }
        }

        private void Form1_Click(object sender, EventArgs e) {
            Point cursor = this.PointToClient(Cursor.Position);

            Refresh();
        }
    }
}


I'm making this into a real game, with classes and all. But keep in mind, this is my second month programming, so don't be harsh ^_^
