Need help making a check statement to make sure al the controls are not blank
<p>This is for a tic tac toe game. I need help making a check statement to see if all the controls' Texts are non-blank, and if they are, you have a draw (if someone had won the previous code would have discovered that). Can you give me a good example using my code.</p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
namespace MyGame
{
    public class Result1
    {


        static private int[,] Winners = new int[,]
                   {
                       // main gameplay Ex: if x is on 0,1,2 x is the winner
                        {0,1,2},
                        {3,4,5},
                        {6,7,8},
                        {0,3,6},
                        {1,4,7},
                        {2,5,8},
                        {0,4,8},
                        {2,4,6},
                   };


        static public bool CheckWinner(Button[] myControls)
        {
            //bolean statement to check for the winner 
            bool gameOver = false;
            for (int i = 0; i &lt; 8; i++)
            {
                int a = Winners[i, 0];
                int b = Winners[i, 1];
                int c = Winners[i, 2];

                Button b1 = myControls[a], b2 = myControls[b], b3 = myControls[c];
                if (b1.Text == "" || b2.Text == "" || b3.Text == "")
                    continue;

                if (b1.Text == b2.Text &amp;&amp; b2.Text == b3.Text)
                {

                    b1.BackColor = b2.BackColor = b3.BackColor = Color.LightCoral;
                    b1.Font = b2.Font = b3.Font = new System.Drawing.Font("Microsoft Sans Serif", 32F, System.Drawing.FontStyle.Italic &amp; System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((System.Byte)(0)));
                    gameOver = true;
                    xWinnerForm xWinnerForm = new xWinnerForm();
                    xWinnerForm.ShowDialog(); //only works with show not showDialog method gets overloaded  (b1.Text + " is the Winner"); to get around this I added and image showing the last player


                }


            }


        return gameOver;
       }





    }
