动态创建控件的问题

Question

I'm having some issues with creating labels dynamically. I'm trying to create a 15x15 grid with an "X" label per cell, and the code is sort of working, it creates the first label but not the others, I've tried debugging the code with breakpoints and it's calling the Controls.Add the right amount of times but it's only creating one label. Here's the code:

class PlayingGrid
{
    const int MAX_CELLS = 15;
    Cell[,] grids = new Cell[MAX_CELLS, MAX_CELLS];

    public PlayingGrid()
    {
        for (int y = 1; y < MAX_CELLS; y++)
        {
            int yPoint = y * 12;

            for (int x = 1; x < MAX_CELLS; x++)
            {
                int xPoint = x * 12;
                grids[y, x] = new Cell(new Point(xPoint, yPoint));
            }
        }
    }
}
class Cell
{
    #region Fields & Properties
    public Letter Letter;
    public Point Point;
    public static GameForm refForm;
    #endregion

    //Default constructor will create an empty cell
    public Cell(Point point)
    {
        Letter = new Letter(LatinAlphabet.Empty);
        this.Point = point;           
        refForm.Invoke(new Action(()=> refForm.Controls.Add(new Label() { Text = "X", Location = point })));
    }
}

Set label AutoSize property to true:

new Label() {AutoSize =true, Text = "X", Location = point }

Because with default size all label hided in below of last label.
