        e.Handled = true;
        MessageBox.Show("Your only allowed to enter letters, Please enter only letters e.g Smith");

You would probably need a Masked Text Box, I am not using that often but I think this would be the syntax:

private void Form1_Load(object sender, EventArgs e)
{
    InitializeComponent();
    maskedTextBox1.Mask = "00/00/0000";
}

This would, when the form is loaded, set the mask of the TextBox that the user can only enter a date.
Hope I helped.
