Doubt for number generation 1

[rubrish]

HI all

I am writing a code for creating a cell with numbers one to nine three in
a row is there any problem with the following code?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;

namespace Sudoku

public partial class SudokuCell : UserControl

{
LighButton = 1,
DarkButton = 2,
ProtectedButton = 3
}

public delegate void FLeftClick(int ID);
public delegate void FRightClick (int ID);

private FLeftClick _LeftClick;
private FRightClick _RightClick;
private CELLMODE _CellMode = CELLMODE.LighButton;

public CELLMODE CellMode
{
get { return _CellMode; }
set
{
_CellMode = value;
switch (_CellMode)
{

this.BackgroundImage = global::Sudoku.Properties.Resources.SudokuCell01;
break;

case CELLMODE.LighButton:
this.BackgroundImage = global::Sudoku.Properties.Resources.SudokuCell02;
break;

case CELLMODE.ProtectedButton:
this.BackgroundImage = global::Sudoku.Properties.Resources.SudokuCell00;
break;
}
}
}
