I'd just use one timer: private int countdown; private void Form1_Load(object sender, EventArgs e) { countdown = 15 * 60; // 15 minutes in seconds timer1.Interval = 1000; // 1 second ShowRemainingTime(); timer1.Start(); } private void timer1_Tick(object sender, EventArgs e) { countdown--; if (countdown == 0) { countdown = 15 * 60; // start again // save something in server } ShowRemainingTime(); } private void ShowRemainingTime() { int mins = countdown / 60; int secs = countdown % 60; label1.Text = String.Format("{0:D2} : {1:D2}", mins, secs); }

Ah, just noticed Brijendra beat me to it but it looks like both our modifications should achieve what you want :)

If you want it to count up when zero is reached and then down again when 900 is reached and carry on like this indefinitely, then the following modified code should do it: private int countdown; private bool towardsZero; private void Form1_Load(object sender, EventArgs e) { countdown = 15 * 60; // 15 minutes in seconds towardsZero = true; timer1.Interval = 1000; // 1 second ShowRemainingTime(); timer1.Start(); } private void timer1_Tick(object sender, EventArgs e) { if (towardsZero) { countdown--; } else { countdown++; } if (countdown == 0 || countdown == 15 * 60) { towardsZero = !towardsZero; // toggle direction // save something in server } ShowRemainingTime(); } private void ShowRemainingTime() { int mins = countdown / 60; int secs = countdown % 60; label1.Text = String.Format("{0:D2} : {1:D2}", mins, secs); }

I've modified Vulpes's code to count up and down: const int MAX_Time = 15 * 60; int interval = 1000; int timerCount = MAX_Time; bool countdown = true; public Form1() { InitializeComponent(); timer1.Interval = interval; timer1.Start(); } private void timer1_Tick(object sender, EventArgs e) { if (countdown) // Count Down { timerCount--; } else //Count Up { timerCount++; } if (timerCount == 0) countdown = false; // Change the counter direction: count up else if (timerCount == MAX_Time) { timer1.Stop(); // Stop the timer //countdown = true; // Change the counter direction: count down } ShowRemainingTime(); } private void ShowRemainingTime() { int mins = timerCount / 60; int secs = timerCount % 60; txtTest.Text = String.Format("{0:D2} : {1:D2}", mins, secs); } Hope this is helpful for you.

Thanks for the Support, There was a small misunderstanding... It worked well for first 15mins and after reaching 0mins, 0secs. It started again to count from 15mins. But my question was after Counting first 15mins i.e after reaching 00:00, it should count up. I mean 00:00 00:01 00:02....so on. anyway it helped me up to some extent... Thank you once again.

Second Timer should start after first timer count to zero.
