Seamless Grids

Funny thing I came across this question today as I am currently working on an A* variation Grid-Search to teach my students next week... Just for testing purposes I made a WinForm with a FlowLayoutPanel control that was 400 x 400 and divided it into and 8x8 Grid resulting in a 50x50 Cell.

I then wrote the following code to populate the panel.

protected List<string> Colors;
protected Color RandomColor()
{
    Color ret;
    /* Truncated Code */
    return ret;
}
private void Form1_Load(object sender, EventArgs e)
{
    Colors = new List<string>();
    Grid8x8.Margin = new System.Windows.Forms.Padding(0);
    Grid8x8.Padding = new System.Windows.Forms.Padding(0);
    Grid8x8.BorderStyle = BorderStyle.FixedSingle;

    Initialize();
}
private void Initialize()
{
    Colors.Clear();
    Grid8x8.Controls.Clear();
    int i;
    for (i = 0; i < 64; i++)
    {
        cell = new Label();
        cell.Text = i.ToString();
        cell.AutoSize = false;
        cell.BorderStyle = BorderStyle.None;
        cell.TextAlign = ContentAlignment.MiddleCenter;
        cell.Width = 50;
        cell.Height = 50;
        cell.Margin = new System.Windows.Forms.Padding(0);

        currentColor = RandomColor();
        previousColor = currentColor;

        cell.BackColor = currentColor;
        Grid8x8.Controls.Add(cell);
        Colors.Add(currentColor.ToString());
    }
}

Since the List is 0-based index instead of a multi-dimensional array its safe to say that if X == CurrentCellIndex then X + 8 will equal the Cell Directly below the CurrentCellIndex.

Hope this helps,
