Use radio buttons. If you really don't want to use them, then subscribe all checkboxes to following CheckedChanged event handler:

private void checkBox_CheckedChanged(object sender, EventArgs e)
{
    CheckBox checkBox = sender as CheckBox;

    if (checkBox.Checked)
        foreach (var other in Controls.OfType<CheckBox>().Where(c => c != checkBox))
            other.Checked = false;
}

Sounds like you should be using radio buttons instead. To do that with check boxes you'll need to manually uncheck the boxes on the .checked event.
