Also, I'm fully aware of what your little snippet does. I guess my question is how to use it. The TableRow doesen't have an OnTextChange event. How do I make create that function?

<br />
private void deleteRegion(object sender, System.Windows.Forms.KeyPressEventArgs e)<br />
        {<br />
<br />
            MessageBox.Show(e.KeyChar.ToString());<br />
<br />
            SplitContainer sc = (SplitContainer)sender;<br />
<br />
            MessageBox.Show("I will delete " + sc.Name);<br />
        }<br />

Can you be more specific?

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
  if ( keyData == Keys.Delete)
  {
    MessageBox.Show("DEL pressed");
  }
  return base.ProcessCmdKey(ref msg, keyData);
}
