title: Why are numeric keypad numbers and regular numbers not the same in KeyEvent?
body: <p>This code does not allow me to enter numeric values from a numeric keypad.</p>
  
  <pre><code>private void textBox1_KeyDown( object sender, KeyEventArgs e ) {
      e.SuppressKeyPress = !( (e.KeyValue &gt;= 48 &amp;&amp; e.KeyValue &lt;= 57) )
  }
  </code></pre>
  
  <p>How can I include numerical values in general (both from regular and number keys)?</p>
