i wrote this code from Mr Jon Skeet answer:
what mistake does it have?because it doesnt do anything when i click,thanks

PictureBox[,] pic = new PictureBox[8, 8];

public PictureBox SetKingImage(int x,int y)
    {


        pic[x,y].Image=Image.FromFile("pic/siyahsah2.JPG");
        return pic[x, y];
    }

public void GetClickedPicturebox()
    {  
        int x, y;

      for(x=0;x<8;x++)
      {
          for(y=0;y<8;y++)
          {
              pic[x, y] = new PictureBox();

              pic[x, y].Click += (object sender, System.EventArgs e) =>SetKingImage(x, y);


            }
          }
      }

The simplest approach would be to ask the user to click on the relevant picture box. You could determine which PictureBox was clicked on in one of three ways:

• Subscribe using the same event handler for each PictureBox, but use a Tag within the PictureBox to get the coordinates
• Subscribe using the same event handler for each PictureBox, but just use the reference to the PictureBox (sender) to find which one it was and get the coordinates appropriately

• Subscribe using a lambda expression which encapsulates the position, like this:

  for (int x = 0; x < 8; x++) {
      for (int y = 0; y < 8; y++) {
          pictureBoxes[x, y].Click += (sender, args) => SetKingPosition(x, y);
      }
  }
  

One problem with the latter approach is that unsubscribing from an event via a lambda expression is relatively painful – and you probably want to unsubscribe all the event handlers when the first button is clicked.

An alternative is to leave the event handlers in place, and ignore them when it’s not the right time 🙂
