Assign OnClick event to each element in an array of PictureBox controls

I have an array of Picture Box controls. Thanks to Expert smegg I can draw them on the Form now.

What I want to do is be able to DETECT a click on each of the 100 picture boxes....and the OnClick will tell me WHICH array element I have clicked on, as in [ X , Y ]

public void InitPictureBoxArray()
            {
                  for(int i=0;i<10;i++)
                  {
                        for(int j=0;j<10;j++)
                        {
                              pBoxArray[i,j] = new System.Windows.Forms.PictureBox();
                              pBoxArray[i,j].Image = gw.gamePieceArray[i,j].pic_box.Image;
                              pBoxArray[i,j].Location=new Point(i*32,j*32);
                              pBoxArray[i,j].Size=new Size(32,32);
                              this.Controls.Add(pBoxArray[i,j]);
                        }
                  }

            }

Making progress:

public void InitPictureBoxArray()
            {
                  for(int i=0;i<10;i++)
                  {
                        for(int j=0;j<10;j++)
                        {
                              pBoxArray[i,j] = new System.Windows.Forms.PictureBox();
                              pBoxArray[i,j].Image = gw.gamePieceArray[i,j].pic_box.Image;
                              pBoxArray[i,j].Location=new Point(i*32,j*32);
                              pBoxArray[i,j].Size=new Size(32,32);
                              pBoxArray[i,j].Click += new System.EventHandler(this.formPictureBox_Click);
                              this.Controls.Add(pBoxArray[i,j]);
                        }
                  }

            }

            private void formPictureBox_Click(object sender, System.EventArgs e)
            {
                  MessageBox.Show(e.ToString());
            }

My guess is I have to cast SENDER as a Picture Box or something?

I don't know how much it is used. :(

They could make is a tad more obvious (perhaps)
