C#

{
   if (!char.IsLetter(e.KeyChar))
   {
      e.Handled = false;
   }
}

Its really simple just add event which you can directly select for designer or in code just write following in constructor

textBox1.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);

C#

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
    if (char.IsDigit(e.KeyChar) || char.IsControl(e.KeyChar))
        {
            e.Handled = true;
    }
        else
        {
            e.Handled = false;
    }
}
