I found this code in a forum, and it works.

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  DataGridViewTextBoxEditingControl tb =(DataGridViewTextBoxEditingControl)e.Control;
  tb.KeyPress += new KeyPressEventHandler(dataGridViewTextBox_KeyPress);

  e.Control.KeyPress += new KeyPressEventHandler(dataGridViewTextBox_KeyPress);
}


private void dataGridViewTextBox_KeyPress(object sender, KeyPressEventArgs e)
