Dispatcher Timer - Windows Phone

Question

I'm building a small app on my windows phone, and I'm having trouble with the dispatcher timer.

Everytime the page is loaded, the dispatcher is being ran over another time.

Basically I got a countdown, when ever the user returns to the mainpage (the countdown), the dispatcher timer is being ran again, this mean, that the countdown is going down twice as fast.

You may post the relevant code to give us a chance to understand what you are doing. — Clemens, Mar 23 '13 at 13:13

Basically the DispatcherTimer is a class that creates a new Thread. So when your page gets reloaded, it creates a new thread. So it is advised to dispose the DispatcherTimer class everytime you navigate away from the class.

DispatcherTimer timer=new DispatcherTimer();


//OnNavigatedFrom(EventArgs e)
{
  timer=null;
}

Even if you navigate to another page, the timer continues to tick! Even if you assign the Timer to another `new` instance in page constructor, the old one continues to tick. Please don't tell that microsoft doesn't suck. Your deal is the only way, if you need a timer to work on specific page only. – Vassilis May 11 '16 at 12:16
