Hi ,

I'm having ASP .NET course and in beginner level , it's too interesting and so powerful .
while my seeking for more information I found your website and it's so useful and helped me to understand unclear subjects .

I'm having a challenge to solve a Home Work , to build Fifteens game in ASP .Net using C# and Web Service , while the Web Service must handle the random fill of table , choose which buttons to be replaced and to visible or invisible and to check end of game .

I have build the Fifteens game in Default.aspx.cs which was my first home work and it's working great here it's :

  using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    private const int sizeBoard = 15;
    private const int sizeRow = 4;
    private int[] arrayIndex = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

    protected void Page_LoadComplete(object sender, EventArgs e)
    {
        if (checkFinalGame())
            showMessage();
        return;
    }


    protected void Page_Load(object sender, EventArgs e)
    {

        createButton();
        createTable();

        if (!Page.IsPostBack)
        {
            TableBtn.BorderStyle = BorderStyle.Inset;
            TableBtn.BorderWidth = Unit.Pixel(3);
            initTable();
        }

    }

    private void createButton()
    {
        for (int i = 0; i < sizeRow; i++)
        {
            for (int j = 0; j < sizeRow; j++)
            {
                
                Button dynamicButton = new Button();
                dynamicButton.ID = i.ToString() + "," + j.ToString();
                dynamicButton.Click += new System.EventHandler(dynamicButton_Click);
                    
                if ((i == sizeRow - 1) && (j == sizeRow - 1))
                {
                    dynamicButton.Visible = false;
                }

                Controls.Add(dynamicButton);
            }
        }
    }

    private void createTable()
    {
        int rows = sizeRow;
        int columns = sizeRow;

        for (int i = 0; i < rows; i++)
        {
            TableRow newRow = new TableRow();
            TableBtn.Controls.Add(newRow);
            for (int j = 0; j < columns; j++)
            {
                TableCell newCell = new TableCell();
                newRow.Controls.Add(newCell);

    private void changeButton(String PrevID, String NextID)
    {

        getButton(NextID).BackColor = getButton(PrevID).BackColor;
        getButton(PrevID).Visible = false;
    }
}

I did learned about Web Service , and I did practice on it but I couldn't implement the required as above ,
Can you please help me ?

Thanks
