Resolved Array receive only two numerical digits in each index

[titojd]

I have problems in my textbox array, there are 15 indexes,
each index receives two digits, however if I type letters it is accepting.

I wanted it to accept only numerical digits, two numbers per index,

Anyone willing to give me some information on how I can proceed with this?
I am very grateful
my code

private TextBox[] ResultText = new TextBox[15];

 private void GeraControles()
        {
            int i, esquerda = 105, topo = 230;
            for (i = 0; i < 15; i++)
            {
                ResultText[i] = new TextBox();
                //ResultText[i].Name = "label" + i;
                //ResultText[i].Text = ResultText[i].Name;
                //ResultText[i].Anchor = AnchorStyles.Right;
                //ResultText[i].Location = new Point(ResultText[i].Location.X + 20, ResultText[i].Location.Y + 300);
                ResultText[i].Left = esquerda;
                ResultText[i].Top = topo;
                ResultText[i].Anchor = new AnchorStyles();
                ResultText[i].BackColor = Color.Gray;
                ResultText[i].ForeColor = Color.White;
                ResultText[i].Size = new Size(45, 30);
                ResultText[i].Font = new Font("", 15, FontStyle.Bold);
                ResultText[i].TabIndex = 2;
                ResultText[i].BorderStyle = BorderStyle.FixedSingle;
                this.Controls.Add(ResultText[i]);
                esquerda += (ResultText[i].Width + 5);
                ResultText[i].Tag = i;
            }
        }

Did you look at the various key press events for your text boxes?

@Skydiver I even managed to do it for a textbox, but for an array I couldn't
I couldn't create the keyPress for the dynamic textBox

 

[Skydiver]

If you can dynamically create textboxes and position them on screen, you can dynamically add key press event handlers to each of those textboxes.

I tried to put KeyPress in the textBox Control ( GeraControles() )

 ResultText[i].KeyPress += new KeyPressEventHandler(keypressed);

then I created the events

private bool nonNumberEntered = false;
        private void ResultText_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
        {
            // Initialize the flag to false.
            nonNumberEntered = false;

            // Determine whether the keystroke is a number from the top of the keyboard.
            if (e.KeyCode < Keys.D0 || e.KeyCode > Keys.D9)
            {
                // Determine whether the keystroke is a number from the keypad.
                if (e.KeyCode < Keys.NumPad0 || e.KeyCode > Keys.NumPad9)
                {
                    // Determine whether the keystroke is a backspace.
                    if (e.KeyCode != Keys.Back)
                    {
                        // A non-numerical keystroke was pressed.
                        // Set the flag to true and evaluate in KeyPress event.
                        nonNumberEntered = true;
                    }
                }
            }
            //If shift key was pressed, it's not a number.
            if (Control.ModifierKeys == Keys.Shift)
            {
                nonNumberEntered = true;
            }
        }
        private void keypressed(Object o, KeyPressEventArgs e)
        {
            // Check for the flag being set in the KeyDown event.
            if (nonNumberEntered == true)
            {
                // Stop the character from being entered into the control since it is non-numerical.
                e.Handled = true;
            }
        }

but I was successful with my code, it keeps entering text and numbers more than two.

I managed to solve my problem here,
I created an 'IntNumber' method in the class program

 static class Program
    {
        /// <summary>
        /// Ponto de entrada principal para o aplicativo.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new frmInicial());
        }
        public static void IntNumber(KeyPressEventArgs e)
        {
            if (!char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar)  && e.KeyChar !=8)
            {
                e.Handled = true;
            }
        }
    }

in the form, I added it to the method that creates the textBox

ResultText[i].MaxLength = 2;
ResultText[i].KeyPress += new KeyPressEventHandler(keypressed);

right after i chemi my method

 private void keypressed(Object o, KeyPressEventArgs e)
        {
            Program.IntNumber(e);
        }

Thanks anyway @Skydrive opened my eyes

Use a NumericUpDown control when you want the user to enter numerics. Hide the spin buttons, and set min 0, max 99 and format 00
