I created a 2D array \[code\]Board\[/code\], holding objects of \[code\]GameCell\[/code\].Default.aspx:\[code\]<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <link rel="stylesheet" href="http://stackoverflow.com/questions/13709048/includes/css/style.css" /></head><body> <form id="form1" runat="server"> <div> <h1>???? ?????</h1> <div id="Board"> <asp:Label ID="Label1" runat="server"></asp:Label> <asp

Maybe the reference wasn't reliable anymore (I saved it in an object) after page_load.
