i have an array of buttons added to a panel control and need to reset them to their original values, is this possible pragmatically?

 protected void Page_Load(object sender, EventArgs e)
{
    RenderTable();
}
private void RenderTable()
{
    Button[] board = new Button[9];
    for(int i =0; i <board.Length; i++)
    {
        board[i] = new Button();
        board[i].Text = " ";
        board[i].Width= board[i].Height = 50;
        board[i].Click += PlayerClick;
        board[i].ID = "pos" + i;
        Panel1.Controls.Add(board[i]);
    }
}
