Stopwatch that counts down in C#
<p>I've seen variations of this by googling it but I have a windows form with a timer control, three textboxes (hour, minute, second) and based on a button being clicked, I want to count down from 2 hours.  So right after clicking textbox1 (hour) will be 1, textBox2 (minute) will be 59, textBox3 (second) will be 59 and they will all continue to count down until all read 0.</p>

<p>Does anyone have some code to share for that?</p>

<p>Many thanks.</p>
