How to get Windows for to raise mouseclick event for programatically created PictureBox?

Question

I'm building a virtual board game, and I need to be able to click on the pieces to move them. The board is created as a picture in the background, and the pieces are pictureboxes over top of that. More specifically, they are a custom class GamePiece that inherits from PictureBox. I know PictureBox has a Name_Click method that is called when it's clicked, but I'm creating my pieces programatically, as follows:

    public Player(int identity, GameBoard Board)
    {
        ID = identity;
        for (int i = 0; i < 4; i++)
        {
            Pieces[i] = new GamePiece(ID, Board.GetPlaceSize(), Board.GetPieceColor(ID), Board);
        }
    }

Therefore, I don't want to hardcode in methods to be called for each Gamepiece, because that would defeat my purpose here.

Any suggestions? I can include any other code that would be helpful, and I'm pretty flexible as far as redesigning code, if that would make my life easier later. Thanks in advance.

Answer 1

Just add Control.Click event handler for your control:

public Player(int identity, GameBoard Board)
{
    ID = identity;
    for (int i = 0; i < 4; i++)
    {
        Pieces[i] = new GamePiece(ID, Board.GetPlaceSize(), Board.GetPieceColor(ID), Board);
        Pieces[i].Tag = ID;
        Pieces[i].Click += pieces_Click;
    }

on the Click event:

private void pieces_Click(object sender, EventArgs e)
{
    int id = (int) ((Pieces))sender.Tag;
    DoSomethingForId(id);
}

or using Anonymous Methods :

public Player(int identity, GameBoard Board)
{
    ID = identity;
    for (int i = 0; i < 4; i++)
    {
        Pieces[i] = new ....
        Pieces[i].Click += (sender, e) =>
                        {
                            // Do some thing
                        };
    }
}

(Wire up to an event handler)

Pieces[i].Click += new EventHandler(theOnClickEvent);

(The event handler)

void theOnClickEvent(object sender, EventArgs e)
    {
        //clicked.
    }

Could it be:

gamePiece.Click += myEventHandler;

Where gamePiece is the GamePiece object, and myEventHandler is any form of event handler... delegate, lambda, whatever.
